soc/amd: introduce SOC_AMD_COMMON_BLOCK_DATA_FABRIC_NP_REGION

Add a separate Kconfig option for adding np_region.c to the build. Only
the code for Picasso, Cezanne, Mendocino, Phoenix and Glinda call
data_fabric_set_mmio_np which is implemented in that file, so only
select the new SOC_AMD_COMMON_BLOCK_DATA_FABRIC_NP_REGION Kconfig option
for those.
