Merge branch 'next/cleanup-s3c24xx' of git://git.kernel.org/pub/scm/l…

…inux/kernel/git/kgene/linux-samsung into next/cleanup

From Kukjin Kim:
Basically, this patch merges mach-s3c2410, mach-s3c2412 and mach-s3c2440
into mach-s3c24xx.

* 'next/cleanup-s3c24xx' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung:
  ARM: S3C24XX: Move mach-s3c2440/ pll into mach-s3c24xx/
  ARM: S3C24XX: Move mach-s3c2440/ cpufreq driver into mach-s3c24xx/
  ARM: S3C24XX: Move mach-s3c2412/ cpufreq driver into mach-s3c24xx/
  ARM: S3C2412: Remove useless codes mach-s3c2412/gpio.c
  ARM: S3C24XX: Move mach-s3c2410/ pll into mach-s3c24xx/
  ARM: S3C24XX: Move mach-s3c2410/ cpufreq into mach-s3c24xx/
