Subject: [PATCH] drm/i915: Restore relaxed padding (OCL_OOB_SUPPRES_ENABLE)
 for skl+

This bit was fliped on for "syncing dependencies between camera and
graphics". BSpec has no recollection why, and it is causing
unrecoverable GPU hangs with Vulkan compute workloads.

>From BSpec, setting bit5 to 0 enables relaxed padding requirements for
buffers, 1D and 2D non-array, non-MSAA, non-mip-mapped linear surfaces;
and *must* be set to 0h on skl+ to ensure "Out of Bounds" case is
suppressed.
