I had to stare at the pps stuff again while dealing with the -stable
pps regression. While doing that I figured I'd try to make it so we
don't accidentally use the wrong pps during the panle probe when we
don't yet have the VBT parsed. So here's an attempt at deducing the
correct pps from the hardware state.
