As exynos_cpuidle_init() and exynos_cpufreq_init() functions have just
one line of code for registering platform devices. So we can move them
to exynos_dt_machine_init() and remove exynos_cpuidle_init() and
exynos_cpufreq_init(). This will help in reducing lines of code in
exynos.c, making it more clean.

Under "arm/mach-exynos" many files are using PMU register offsets.
Since we have added support for accessing PMU base address via DT,
now we can remove PMU mapping from exynosX_iodesc. Let's convert
all these access using iomapped address.
This will help us in removing static mapping of PMU base address
as well as help in reducing dependency over machine header files.
Thus helping for migration of PMU implementation from machine to
driver folder which can be reused for ARM64 based SoC.
Also as we have removed static mappings from "regs-pmu.h" it does
not need map.h anymore. But "platsmp.c" needed this and till now it
got included indirectly. So lets move header inclusion of
"mach/map.h" from "regs-pmu.h" to "platsmp.c".

Turning off a cluster when all 4 cores of the cluster are powered off
saves power significantly. Powering off the A15 L2 alone gives around
100mW in savings. Add support for powering off the A15/A7 clusters on
exynos5420/5800.
The patch enables specific register bits which ensure that:
- cluster L2 will be turned on before the first man is powered up.
- last man will be turned off before the cluster L2 is turned off.
- core is powered down before powering it up.
Remove the exynos_cluster_power_control function completely as we can
rely on the above mentioned bits rather than polling the cluster power
status register.

The i.MX6 reference manual doesn't make a clear distinction
between the fixed clock divider and the enable gate for the
pcie and sata reference clocks. This lead to the lvds mux
inputs in the imx6q clk driver to be parented from the
ref clock (which is the divider) instead of the actual gate,
which in turn prevents the upstream clock to actually be
enabled when lvds clk out is active.
This fixes a hard machine hang regression in kernel 3.16 for
boards where only pcie is active but no sata, as with this
kernel version the imx6-pcie driver is no longer enabling
the upstream clock directly but only lvds clk out.

correct kind of cookie as the argument, from Loic Prylli.
