[ARM] S3C24XX: Split pll code out of regs-clock.h
Move the PLL calculation code into it's own header
file for re-use with the other plat-s3c24xx based
systems such as the S3C24A0.
Note, we change the name of s3c2410_get_pll to the
more generically named s3c24xx_get_pll as well as
the related defintions.
