ARM: EXYNOS: switch to using generic cpufreq driver for exynos4x12
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).
