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.
