[U-Boot] [PATCH] powerpc/p2041: fix serdes reference clock frequency for PC board
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.
