[PATCH] drm/i915/mtl: Update workaround 14018778641

[Chen, Angus]

The original workaround was from 
https://patchwork.freedesktop.org/patch/533574/
Then, we don't apply WA to VDBOX, VEBOX and RENDER engine with
the following patch 
https://patchwork.freedesktop.org/patch/543117/?series=119517&rev=1
But now we need this WA to cover VDBOX.
