Fix TBI PHY accesses to use the proper offset in CPU register space. The previous code would incorrectly access the TBI PHY by reading/writing to CPU register space at the same location as would be used to access external PHYs.

I replaced the hardcoding of CFG_TBIPA_VALUE in the tsec_configure_serdes() to support possible changes of the TBI addressing down the road, but kept the default TBI PHY address at CFG_TBIPA_VALUE as Andy Flemming suggested.
