This moves regarding exynos-cpufreq definitions into drivers/cpufreq/
exynos-cpufreq.h because they are used only for the cpufreq driver.

* remove superfluous pr_debug() call from exynos_cpufreq_init()
  (init errors are always logged anyway)
* add dummy per-SoC type init functions to exynos-cpufreq.h
* make per-SoC type cpufreq config options selectable
* make CONFIG_ARM_EXYNOS_CPUFREQ config option invisible to user and
  automatically enable it when needed

This patch fixes following issues:
* EXYNOS per-SoC type cpufreq support (i.e. exynos4210-cpufreq.c) being
  always built if given SoC support was enabled (i.e. CPU_EXYNOS4210),
  even if common EXYNOS cpufreq support was disabled
* inability to select cpufreq for each SoC type separately (it could
  be only enabled/disabled for all SoCs for which support was enabled)
* EXYNOS5440 cpufreq support was always enabled when EXYNOS5440
  support was enabled and couldn't be disabled

The variable 'max_support_idx, min_support_idx, pm_lock_idx"
are never used, so remove the unused variable.

This patch adds support cpufreq for EXYNOS5250 SoC. Basically,
the exynos-cpufreq.c is used commonly and exynos5250-cpufreq.c
is used for EXYNOS5250(two Cortex-A15 cores) SoC.

To support various EXYNOS series SoCs commonly,
added exynos common structure.
exynos-cpufreq.c => EXYNOS series common cpufreq driver
exynos4210-cpufreq.c => EXYNOS4210 support cpufreq driver
