Instead of passing util and max between functions while computing the
utilization and capacity, store the former in struct sg_cpu (along
with the latter and bw_dl).
This will allow the current utilization value to be compared with the
one obtained previously (which is requisite for some code changes to
follow this one), but also it causes the code to look slightly more
consistent and cleaner.

The cppc_cpudata per-cpu storage was inefficient (1) additional to causing
functional issues (2) when CPUs are hotplugged out, due to per-cpu data
being improperly initialised.
(1) The amount of information needed for CPPC performance control in its
cpufreq driver depends on the domain (PSD) coordination type:
ANY: One set of CPPC control and capability data (e.g desired
performance, highest/lowest performance, etc) applies to all
CPUs in the domain.
ALL: Same as ANY. To be noted that this type is not currently
supported. When supported, information about which CPUs
belong to a domain is needed in order for frequency change
requests to be sent to each of them.
HW: It's necessary to store CPPC control and capability
information for all the CPUs. HW will then coordinate the
performance state based on their limitations and requests.
NONE: Same as HW. No HW coordination is expected.
Despite this, the previous initialisation code would indiscriminately
allocate memory for all CPUs (all_cpu_data) and unnecessarily
duplicate performance capabilities and the domain sharing mask and type
for each possible CPU.
(2) With the current per-cpu structure, when having ANY coordination,
the cppc_cpudata cpu information is not initialised (will remain 0)
for all CPUs in a policy, other than policy->cpu. When policy->cpu is
hotplugged out, the driver will incorrectly use the uninitialised (0)
value of the other CPUs when making frequency changes. Additionally,
the previous values stored in the perf_ctrls.desired_perf will be
lost when policy->cpu changes.
Therefore replace the array of per cpu data with a list. The memory for
each structure is allocated at policy init, where a single structure
can be allocated per policy, not per cpu. In order to accommodate the
struct list_head node in the cppc_cpudata structure, the now unused cpu
and cur_policy variables are removed.
For example, on a arm64 Juno platform with 6 CPUs: (0, 1, 2, 3) in PSD1,
(4, 5) in PSD2 - ANY coordination, the memory allocation comparison shows:
Before patch:
- ANY coordination:
total slack req alloc/free caller
0 0 0 0/1 _kernel_size_le_hi32+0x0xffff800008ff7810
0 0 0 0/6 _kernel_size_le_hi32+0x0xffff800008ff7808
128 80 48 1/0 _kernel_size_le_hi32+0x0xffff800008ffc070
768 0 768 6/0 _kernel_size_le_hi32+0x0xffff800008ffc0e4
After patch:
- ANY coordination:
total slack req alloc/free caller
256 0 256 2/0 _kernel_size_le_hi32+0x0xffff800008fed410
0 0 0 0/2 _kernel_size_le_hi32+0x0xffff800008fed274
Additional notes:
- A pointer to the policy's cppc_cpudata is stored in policy->driver_data
- Driver registration is skipped if _CPC entries are not present.

Considering only the currently supported coordination types (ANY, HW,
NONE), this change only makes a difference for the ANY type, when
policy->cpu is hotplugged out. In that case the new policy->cpu will
be different from ((struct cppc_cpudata *)policy->driver_data)->cpu.
While in this case the controls of *ANY* CPU could be used to drive
frequency changes, it's more consistent to use policy->cpu as the
leading CPU, as used in all other cppc_cpufreq functions. Additionally,
the debug prints in cppc_set_perf() would no longer create confusion
when referring to a CPU that is hotplugged out.

For errors parsing the _PSD domains, a separate domain is returned for
each CPU in the failed _PSD domain with no coordination (as per previous
comment). But contrary to the intention, the code was setting
CPUFREQ_SHARED_TYPE_ALL as coordination type.
Change shared_type to CPUFREQ_SHARED_TYPE_NONE in case of errors parsing
the domain information. The function still returns the error and the caller
is free to bail out the domain initialisation altogether in that case.
Given that both functions return domains with a single CPU, this change
does not affect the functionality, but clarifies the intention.

In Virtualization case, when one VF is sending too many
FLR requests, hypervisor would stop responding to this
VF's request for a long period of time. This is called
event guard. During this period of cooling time, guest
driver should wait instead of doing other things. After
this period of time, guest driver would resume reset
process and return to normal.
Currently, guest driver would wait 12 seconds and return fail
if it doesn't get response from host.
Solution: extend this waiting time in guest driver and poll
response periodically. Poll happens every 6 seconds and it will
last for 60 seconds.

The memblock code ignores any memory that doesn't fit in the
linear mapping. In order to preserve the distance between two physical
memory locations and their mappings in the linear map, any hole between
two memory regions occupies the same space in the linear map.
On most systems, this is hardly a problem (the memory banks are close
together, and VA_BITS represents a large space compared to the available
memory *and* the potential gaps).
On NUMA systems, things are quite different: the gaps between the
memory nodes can be pretty large compared to the memory size itself,
and the range from memblock_start_of_DRAM() to memblock_end_of_DRAM()
can exceed the space described by VA_BITS.
Unfortunately, we're not very good at making this obvious to the user,
and on a D05 system (two sockets and 4 nodes with 64GB each)
accidentally configured with 39bit VA, we display something like this:
[ 0.000000] NUMA: NODE_DATA [mem 0x1ffbffe100-0x1ffbffffff]
[ 0.000000] NUMA: NODE_DATA [mem 0x2febfc1100-0x2febfc2fff]
[ 0.000000] NUMA: Initmem setup node 2 [<memory-less node>]
[ 0.000000] NUMA: NODE_DATA [mem 0x2febfbf200-0x2febfc10ff]
[ 0.000000] NUMA: NODE_DATA(2) on node 1
[ 0.000000] NUMA: Initmem setup node 3 [<memory-less node>]
[ 0.000000] NUMA: NODE_DATA [mem 0x2febfbd300-0x2febfbf1ff]
[ 0.000000] NUMA: NODE_DATA(3) on node 1
which isn't very explicit, and doesn't tell the user why 128GB
have suddently disappeared.
Let's add a warning message telling the user that memory has been
truncated, and offer a potential solution (bumping VA_BITS up).
