Since we switch to use generic syscon regmap based reset/poweroff
driver for exynos SoC, lets select it from ARCH_EXYNOS instead of
enabling it from various defconfigs. This also select POWER_RESET
as SYSCON-{reset, poweroff} drivers depends on it.

Also because of the above changes we don't need special handling
for reboot/poweroff in exynos pmu driver. This patch also removes
the same from exynos pmu driver to keep git bisect working.

Note: This will break reboot/poweroff on boards with older dtbs
with a newer kernel.

The new CPU clock type allows the use of generic CPUfreq driver.
Switch Exynos4x12 to using generic cpufreq driver.

Previously (when exynos-cpufreq driver was used with boost
functionality) ARM_EXYNOS_CPU_FREQ_BOOST_SW config option
(which enabled boost functionality) selected EXYNOS_THERMAL
one. After switching Exynos4x12 platforms to use cpufreq-dt
driver boost support is enabled in the cpufreq-dt driver
itself (because there are turbo OPPs defined in the board's
DTS file). However we still would like to allow enabling
boost support only if thermal support is also enabled for
Exynos platforms. To achieve this make ARCH_EXYNOS config
option select THERMAL and EXYNOS_THERMAL ones.

Please also note that the switch to use the generic cpufreq-dt
driver fixes the minor issue present with the old code (support
for 'boost' mode in the exynos-cpufreq driver was enabled for
all supported SoCs even though 'boost' frequency was provided
only for Exynos4x12 ones).

This patch separates the PMU driver code from the low level
CCI driver code and enables the PMU driver for ARM64.

Introduces config options for both.

 ARM_CCI400_PORT_CTRL	- controls the low level driver code for

 ARM_CCI400_PMU		- controls the PMU driver code
 ARM_CCI400_COMMON	- Common defintions for CCI400

This patch also changes:
 ARM_CCI - common code for probing the CCI devices. This can be
   used for adding support for newer CCI versions(e.g, CCI-500).

implementation in following way:

- Added platform driver support for Exynos PMU IP.
- Added platform struct exynos_pmu_data to hold platform specific data.
- For each SoC's PMU support now we can add platform data and statically
  bind PMU configuration and SoC specific initialization function.
- Separate each SoC's PMU initialization function and make it as part of
  platform data.
- It also removes uses of soc_is_exynosXYZ().
