drm/i915/mtl: Disable C6 on MTL A0 for media
Earlier merge dropped an if block when applying the patch -
"drm/i915/mtl: Synchronize i915/BIOS on C6 enabling". Bring back the
if block as the check is required by - "drm/i915/mtl: Disable MC6 for MTL
A step" to disable C6 on media for A0 stepping.
Fixes: 3735040978a4 ("drm/i915/mtl: Synchronize i915/BIOS on C6 enabling")
