nb/amd/mct_ddr3: Consolidate duplicated code

read_dqs_read_data_timing_registers() and
    read_read_dqs_timing_control_registers() served essentially
    the same function but had slightly different semantics,
    causing confusion and needlessly complex Family15h code.

Consolidate both into read_dqs_read_data_timing_registers()
    and adjust surrounding code to match new semantics.
