drm/i915: Set output_types to EDP for vlv/chv DPLL forcing

When we enable the DPLL for the PPS kick, let's tell the DPLL code
we're dealing with an eDP output. This shouldn't really matter, but
it's more consistent with the way the DPLL is configured when we're
actually enabling the eDP port for real.
