Single frame update is a feature available on BDW for PSR that allows Source to send Sink only one frame and get it updated. Usually useful when page flipping. However with our frontbuffer tracking where we force psr exit on flips we don't need this feature.
Also after it got added here many workaround was added to documentation to mask some bits when using single frame update. So the safest thing is to just stop using it. v2: Rebase after removing skip aux one and fixing typo on commit message.
