drm/i915/tgl: allow DVI/HDMI on port A

Browse source 
Tiger Lake supports HDMI on port A. For other platforms we ignore what
the VBT says regarding HDMI to workaround broken VBTs, see
commit 2ba7d7e043 ("drm/i915/bios: ignore HDMI on port A"). Make this
apply gen12+ so they inherit the TGL behavior.
