powerpc/85xx: Extend SERDES9 erratum work-around to SGMII, SRIO, and AURORA

Part of the SERDES9 erratum work-around is to set some bits in the SerDes
TTLCR0 register for lanes configured as XAUI, SGMII, SRIO, or AURORA.  The
current code does this only for XAUI, so extend it to the other protocols.
