Rahul Sharma 976face4b4 clk/samsung: add support for multiple clock providers 
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.

[t.figa: Modified s3c2410 clock driver as well]
