Daniel pointed out offline that in the !fastboot case, this will fail
to do the pipe size update if we ever try to skip the mode set when
changing the pfit state.

To address that we'll need to handle the pfit changes more generally
anyway, which gets tricky when we're trying to discard the BIOS state.

Ander, if you want to tackle this as part of your multi-pipe stuff,
feel free, otherwise I'll get to it after the holidays.

Thanks,
