Niranjana Vishwanathapura 752600f1ac drm/xe: Ensure fixed_slice_mode gets set after ccs_mode change
commit 262de94a3a upstream.

The RCU_MODE_FIXED_SLICE_CCS_MODE setting is not getting invoked
in the gt reset path after the ccs_mode setting by the user.
Add it to engine register update list (in hw_engine_setup_default_state())
which ensures it gets set in the gt reset and engine reset paths.

v2: Add register update to engine list to ensure it gets updated
after engine reset also.
