gma-display_probing: Only check display type on DVI-I

On DVI-I connectors the DDC is shared between the analog and digital
parts. To decide which path to take we checked the digital input bit
of the EDID. We did this overeagerly for all ports, which broke com-
patibility with DP adapters (the DP realm is very complex and we are
supposed to discover the whole downstream hierarchie, which obviously
would be overkill).
