drm/xe: Apply Wa_16023105232

Browse source

The WA requires KMD to disable DOP clock gating during a semaphore
wait and also ensure that idle delay for every CS is lower than the
idle wait time in the PWRCTX_MAXCNT register. Default values for these
registers already comply with this restriction.

v2: Store timestamp_base in gt info and other comments (Daniele)
v3: Skip WA check for VF
v4: Review comments (Matt Roper)
v5: Cleanup the clock functions and use reg_field_get (Matt Roper)
v6: Fix checkpatch issue
v7: Fix CI issue
