arm: mvebu: a38x: Remove unsupported topologies

A lot of extra configuration information was left over in the
Marvell serdes and DDR3 initialization code for boards that
U-boot does not support.  Remove this extra config information,
and the concept of fixing up board topologies with information
loaded from an EEPROM.  If this needs to be done, it should be
handled in the board file, not in core code.
