Samsung CCF helper functions do not provide support to
register multiple Clock Providers for a given SoC. Due to
this limitation, SoC platforms are not able to use these
helpers for registering multiple clock providers and are
forced to bypass this layer.

This layer is modified accordingly to enable the support
for multiple clock providers.

Clock file for exynos4, exynos5250, exynos5420, exynos5440,
S3c64xx, S3c24xx are also modified as per changed helper functions.

This driver can handle the clock controller in the s3c2412 soc.

The clock structure is built according to the manuals of the included
SoCs and might include changes in comparison to the previous clock
structure.
