The new CPU clock type allows the use of generic CPUfreq driver.
Switch Exynos4x12 to using generic cpufreq driver.
Also make CPUFREQ_DT config option select Exynos thermal driver
if Exynos platform support is enabled.
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 adds a generic DT based cpufreq driver for frequency management.
It supports both uniprocessor (UP) and symmetric multiprocessor (SMP)
