powerpc/85xx: Implement work-around for P4080 erratum SERDES-A001
Bank powerdown through RCW[SRDS_LPD_Bn] for XAUI on FM2 and SGMII on FM1
are swapped.
Erratum SERDES-A001 says that if bank two is kept disabled and after bank
three is enabled, then the PLL for bank three won't lock properly. The
work-around is to enable and then disable bank two after bank three is
enabled.
