mpc83xx: Fix the SATA clock setting of 837x targets
Currently the SATA controller clock is configured as CSB clock, usually the CSB clock is 400/333/266MHz. However, The SATA IP block is only guaranteed to operate up to 200 MHz as stated in the HW spec. The bug is reported by Joe D'Abbraccio <ljd015@freescale.com> This patch makes the SATA clock as half of CSB clock.
