soc/amd/*/data_fabric: introduce and use DF_MMIO_REG_SET_SIZE
To be able to handle a special case, add a per-SoC define for
DF_MMIO_REG_SET_SIZE instead of having this hard-coded as 4 in the
DF_MMIO_* macros. To avoid some duplication, also introduce the
DF_MMIO_REG_OFFSET macro.
TEST=Output from data_fabric_print_mmio_conf doesn't change on Mandolin.
