From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
When we have no VBT we currently assume ports A-F are
all pontially valid for every platform. That is nonsense.
Grab the bitmask of valid ports from the runtime info
instead.
Although the defaults we actually fill here look semi-sensible
only for hsw-skl era hardware. Dunno if we should try to do
something more appropriate here for other platforms,
or just try to nuke the whole thing?
