[ARM] 4790/1: S3C2412: Fix parent selection for msysclk.
The msysclk clock was checking for the wrong PLL for the parent in s3c2412_setparent_msysclk(), trying the UPLL instead of the MPLL output. Also ensure the mpll and fclks are at the same rate at init time. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
