...
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.

drm/i915/guc/rc: Setup and enable GuCRC feature
...
This feature hands over the control of HW RC6 to the GuC.
GuC decides when to put HW into RC6 based on it's internal
busyness algorithms.
GuCRC needs GuC submission to be enabled, and only
supported on Gen12+ for now.
When GuCRC is enabled, do not set HW RC6. Use a H2G message
to tell GuC to enable GuCRC. When disabling RC6, tell GuC to
revert RC6 control back to KMD. KMD is still responsible for
enabling everything related to Coarse Power Gating though.
v2: Address comments (Michal W)
v3: Don't set hysterisis values when GuCRC is used (Matt Roper)
v4: checkpatch()
