Googling for users of the firmware's hdmi_drive= flag, I'm seeing lots
of people with hdmi_drive=2 (force HDMI mode) due to Raspberry Pi not
allowing HDMI audio with DMT modes, which it looks like DRM does allow.

The only users of hdmi_drive=1 (force HDMI mode) I'm seeing are people
setting things up for non-EDID monitors, but I think the expectation in
DRM is that people would provide an EDID.  So, I'm not sure it makes
sense to support an equivalent of this flag?  Or, it should probably be
part of specifying a custom mode on the command line.
