soc/amd/common/data_fabric_helper: add comment about cfg_inst_acc_en

Since all indirect data fabric register accesses will be non-broadcast
accesses that target a specific data fabric instance, the
cfg_inst_acc_en bit in the DF_FICAA_BIOS register will always be set
since that makes the indirect access target only a specific data fabric
instance.
