Subject: drm/i915/guc: Add disable interrupts to guc sanitize
Git-commit: e5a1ad035938e60448cc0cd334359885c4fd3054
Patch-mainline: v5.15-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

Add disable GuC interrupts to intel_guc_sanitize(). Part of this
requires moving the guc_*_interrupt wrapper function into header file
intel_guc.h.
