Wondering if it was WAIT_FOR_RC6_EXIT (seen in gen12_oa_mux_regs) which

WAIT_FOR_RC6_EXIT (0x20cc) moved elsewhere so it should be "removed"

I will break them into separate patches though. If the diff is
identical, I will carry over your R-b on the split patches. Please let
me know if that's a concern.
Thanks,

If you decide to split the patches, please add my R-b on all the split patches.
