MACH SAMSUNG/S3C: Separate the clocksource for the S3C family ...

This patch just move the clocksource functions out of the generic.c source file
to handle it on a per CPU base later on.

MACH SAMSUNG/S3C: Separate S3C24XX clock management ...

There are major differences in the clock tree of the S3C24xx family and the
more recent CPUs of the S3C family. Keep the S3C24XX clock routines separate to
avoid an ifdef hell. But also use generic function names to be able to
share drivers among the S3C family.

MACH SAMSUNG: Rename the whole mach to add more CPUs in future ...

The S3Cxxxx family consists of ARMv4, ARMv5 and ARMv6 types of CPU cores. The
S3C24xx sub family is only one of it. To be able to handle all CPUs in one mach
directory, use a more generic name for it.
