drm/i915/bios: ignore HDMI on port A
commit 2ba7d7e0437127314864238f8bfcb8369d81075c upstream.
The hardware state readout oopses after several warnings when trying to
use HDMI on port A, if such a combination is configured in VBT. Filter
the combo out already at the VBT parsing phase.
v2: also ignore DVI (Ville)
