Subject: [RESPIN PATCH v6] ARM: EXYNOS: Move cpufreq and cpuidle device
 registration to init_machine

As exynos_cpuidle_init and exynos_cpufreq_init function have just one lines
of code for registering platform devices. We can move these lines to
exynos_dt_machine_init and delete exynos_cpuidle_init and exynos_cpufreq_init
function. This will help in reducing lines of code in exynos.c, making it
more cleaner.
