This workaround is added for Media tile of MTL A step. It is to help
pcode workaround which handles the hardware issue seen during package C2/C3
transitions due to RC6 entry/exit transitions on Media tile. As a part of
workaround pcode expect kmd to send mailbox message "media busy" when
components of Media tile are in use and "media idle" otherwise.
As per workaround description gucrc need to be disabled so enabled
host based RC for Media tile.
