rk3288: Auto-detect display.
We currently select either HDMI or EDP (default). This patch
allows us to use HDMI as a fallback for devices that may have
a display connected on either interface. It also renames the
enums to sound a little more sensible in other contexts (more
on that in the follow-up patches).
VOP_MODE_AUTO is added to the mode enum which will make it explicit
that a board can support either. In AUTO_MODE we will try EDP first
and then fallback to HDMI. Other modes can be set to force a certain
behavior such as HDMI-only on Mickey where it doesn't make sense to
try EDP.
A follow-up patch will add logic for when we explicitly don't want
to probe for any display (headless devices).
BUG=none
BRANCH=none
TEST=On veyron_danger, connected EDP and HDMI displays and saw dev
mode screen appear on EDP display. Unplugged EDP and then dev mode
screen showed up on HDMI.
