soc/amd: drop unneeded data_fabric_set_mmio_np

Drop the unneeded data_fabric_set_mmio_np function and the corresponding
SOC_AMD_COMMON_BLOCK_DATA_FABRIC_NP_REGION Kconfig symbol. In systems
with only one FCH, its MMIO region will be subtractively decoded and
there's no need to add a non-posted data fabric MMIO region after the
FSP/openSIL has already configured the data fabric decode windows. In
systems with more than one FCH, openSIL will already take care of
initializing everything for the additional FCH, so we also won't need to
do anything in that case. Since dropping this function also removes both
data_fabric_print_mmio_conf calls before and after adding the unneeded
non-posted MMIO region, replace the data_fabric_set_mmio_np call with a
data_fabric_print_mmio_conf call to still print the data fabric MMIO
decode regions set up by the FSP/openSIL.
