drm/i915: crt fetch EDID by DVI-I converter on G4x platform

Usually crt mainly get modes via GPIOA ports.
However on G4X platform we need to probe possible
ports for DVI-I, which could be wired to GPIOD,
then fetch our desired EDID, i.e on DG45ID platform
we successfully fetch EDID by GPIOD port.

It fixed freedesktop.org bug #21084
