Remove __init section placement for some functions, so that we don't
get section mismatch warnings.
[v2]:
2 of them were not caught by
DEBUG_SECTION_MISMATCH=y
magic. Fix it.

Perform same-cluster checking even for masks with all (nr_cpu_ids)
bits set and report correct apicid on success instead.
While at it, convert it to for_each_cpu and newer cpumask api.

Remove es7000_cpu_mask_to_apicid_cluster completely, because it's
almost the same as es7000_cpu_mask_to_apicid except 2 code paths.
One of them is about to be removed soon, the another should be
BAD_APICID (it's a fail path).
The _cluster one was not invoked on apic->cpu_mask_to_apicid_and
anyway, since there was no _cluster_and variant.
Also use newer cpumask functions.

The ones which go only into struct apic are de-inlined
by compiler anyway, so remove the inline specifier from them.
Afterwards, remove bigsmp_setup_portio_remap completely as it
is unused.

Impact: build fix
init_deasserted is only available on SMP. Make the secondary-wakeup
function conditional on SMP.
Also clean up the file some.

Impact: cleanup
- rename apic->wakeup_cpu to apic->wakeup_secondary_cpu, to
make it apparent that this is an SMP-only method
- handle NULL ->wakeup_secondary_cpus to mean the default INIT
wakeup sequence - this allows simplification of the APIC
driver templates.

x86_quirks->update_apic() calling looks crazy. so try to remove it:
1. every apic take wakeup_cpu member directly
2. separate es7000_apic to es7000_apic_cluster
3. use uv_wakeup_cpu directly

The ones which go only into struct genapic are de-inlined
by compiler anyway, so remove the inline specifier from them.
Afterwards, remove summit_setup_portio_remap completely as it
is unused.
Remove inline also from summit_cpu_mask_to_apicid, since it's
not worth it (it is used in struct genapic too).

Make x86_quirks support more transparent. The highlevel
methods are now named:
extern void x86_quirk_pre_intr_init(void);
extern void x86_quirk_intr_init(void);
extern void x86_quirk_trap_init(void);
extern void x86_quirk_pre_time_init(void);
extern void x86_quirk_time_init(void);
This makes it clear that if some platform extension has to
do something here that it is considered ... weird, and is
discouraged.
Also remove arch_hooks.h and move it into setup.h (and other
header files where appropriate).

If BIOS hands over the control to OS in legacy xapic mode, select
legacy xapic related ops in the early apic probe and shift to x2apic
ops later in the boot sequence, only after enabling x2apic mode.

This fixes the early boot panic, where we were selecting x2apic ops,
while the cpu is still in legacy xapic mode.

arch/x86/kernel/ is getting a bit crowded, and the APIC
drivers are scattered into various different files.
Move them to arch/x86/kernel/apic/*, and also remove
the 'gen' prefix from those which had it.
Also move APIC related functionality: the IO-APIC driver,
the NMI and the IPI code.
