drm/xe: Get hwe domain specific FW to read RING_TIMESTAMP
Per client engine utilization uses RING_TIMESTAMP to return
drm-total-cycles to the user. Current code uses XE_FW_GT to read this
register on the first available engine in a GT. When testing on DG2, it
is observed that this value is 0 when running test on some engines. To
resolve that, get the hwe domain specific FW for reading the engine
timestamp.
v2:
- update commit message
- use domain specific FW (Matt)
v3:
- Drop check for hwe in the helper (Matt, Michal)
v4:
- checkpatch fixes
v5: Rebase
Fixes: 188ced1e0ff8 ("drm/xe/client: Print runtime to fdinfo")
