drm/i915/mtl: Update workaround 14018575942drm-intel-gt-next-2024-06-12
The WA should be extended to cover VDBOX engine. We found that
28-channels 1080p VP9 encoding may hit this issue.
v3: update the WA number and explain the reason why
this workaround is needed
v2: add WA number
v1: initial version
