Merge tag 's3c24xx-clk' of http://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/cleanup

Merge "Samsung S3C24XX updates for 3.16" from Kukjin Kim:

Samsung S3C24XX to use the common clock framework
- S3C2412, S3C2413, S3C2416 and S3C2443 to use CCF
- S3C2410, S3C2440, S3C2442 to use CCF
- Remove legacy samsung clock from mach-s3c24xx/

- Some of them are missed from previous pull-request
- Clock related sutff got ack from Mike and Tomasz
- Created the last commit due to missing changes
  during re-sorting because this branch is provided
  as a base to samsung clk tree.
