powerpc/p2041: fix serdes reference clock frequency display for PC board

Browse source 
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.
