drm/i915/pps: Reinit PPS delays after VBT has been fully parsed

During the eDP probe we may not yet know the panel_type used
to index the VBT panel tables. So the initial eDP probe will have
to be done without that, and thus we won't yet have the PPS delays
from the VBT. Once the VBT has been fully parse we should reinit
the PPS delays to make sure it's fully accounted for.
