On Exynos5422 and Exynos5800 we support 12 cpufreq steps (200-1300 MHz) for LITTLE
and 18 steps for big core (200-1700 MHz). Add respective cooling cells.

For Exynos542x/5800 platforms, add CPU operating points
for migrating from Exynos specific cpufreq driver to using
generic cpufreq driver.

Exynos5420 and Exynos5800 boards boot from big core (A15) but
Exynos5422 boards choose otherwise: LITTLE core (A7) (on Exynos5422 this
is property of the board - configurable by pulling up/down gpg2-1).
To make user-visible CPU ordering more consistent the 'cpus' node was
overridden by exynos5422-cpus.dtsi.
However this is a little bit ugly and error-prone. Overriding the CPU
child nodes requires to basically reverse what was done initially in
exynos5420.dtsi.
Instead, split CPU configuration entirely to separate files which should
be included by board DTS.

The odroid-xu3 board which is based on exynos5422 not exynos5800
is booted from cortex-a7 core unlike exynos5800. The odroid-xu3's
cpu order is quite strange. cpu0 and cpu5-7 are cortex-a7 cores and
cpu1-4 are cortex-a15 cores. To correct this mis-odering, I added
exynos5422-cpus.dtsi and reversing cpu orders from exynos5420.
Now, cpu0-3 are cortex-a7 and cpu4-7 are cortex-a15.
