drm/i915/gt: Automate CCS Mode setting during engine resets
We missed setting the CCS mode during resume and engine resets.
Create a workaround to be added in the engine's workaround list.
This workaround sets the XEHP_CCS_MODE value at every reset.
The issue can be reproduced by running:
$ clpeak --kernel-latency
Without resetting the CCS mode, we encounter a fence timeout:
Fence expiration time out i915-0000:03:00.0:clpeak[2387]:2!
