[PATCH 5.10 142/152] drm/i915/gt: Restore clear-residual mitigations for Ivybridge, Baytrail

[Greg Kroah-Hartman]

From: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx>

commit 09aa9e45863e9e25dfbf350bae89fc3c2964482c upstream.

The mitigation is required for all gen7 platforms, now that it does not
cause GPU hangs, restore it for Ivybridge and Baytrail.
