Subject: drm/i915/gt: use get_reset_domain() helper
Git-commit: 64b2a6a054c40c04a4e48fd70002570654381f9c
Patch-mainline: v5.18-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
We dont need to implement reset_domain in intel_engine
_setup(), but can be done as a helper. Implemented as
engine->reset_domain = get_reset_domain().
