I didn't look at the exact code path, but if we're using pdata-quirks,
the of_node in struct device passed to vpif_probe is NULL (one of the
reasons why we're not mixing DT and pdata for vpif subdevices
configuration etc.). So it seems that as long as we don't switch over
to DT entirely we need to have the GPIOs here as well.

Thanks,
