Subject: drm/i915/icl: Verify engine workarounds in GEN8_L3SQCREG4
Git-commit: 935ba6f3bf0fad42aac2b10d19498cf27c33cc98
Patch-mainline: v5.4-rc1
References: bsc#1152489
Having fixed the incorect MCR programming in an earlier patch, we can now
stop ignoring read back of GEN8_L3SQCREG4 during engine workaround
verification.
