PC board has different serdes clock setting with PB board, it uses same serdes frequency setting on bank2 as on bank1. PC board can be distingushed from PB board by checking CPLD version, if running on PC board, then fix the serdes reference clock frequency of bank2.

Signed-off-by: Shaohui Xie Shaohui.Xie@freescale.com --- changes for v2: fix logical error and use braces around multi-line if bodies.
