include: mailbox: rpmi_msgprot: Add RPMI performance domain flag defines

Browse Source 
Add bit-field defines for the RPMI performance domain attributes flags
and fast-channel attributes flags as specified in the RPMI specification.
These are needed by platform implementations that provide RPMI
performance services (e.g. DVFS controllers).

Also add the missing db_write_value field to
rpmi_perf_get_fast_chn_attr_resp to match the RPMI spec layout.
