Just like we do in the HDMI code, set the infoframe flag if we detect an
HDMI sink.

Infoframes aren't controlled by this bit here but set in
HSW_TVIDEO_DIP_CTL. Since the point of this is to detect mismatches
between the bios and what we'd like to have for fastboot I think we need
to check that register. Instead of blindly deriving state to appease the
cross checker.

Oh you're right; I was thinking of compute_config.  I'll send a follow
up.
