veyron_danger: Add basic HDMI support
This adds a configure_hdmi() function that drives the HDMI
enable output high and configures the iomux.
We'll add EDP/HDMI auto-detection in an upcoming patch.
BUG=none
BRANCH=none
TEST=set vop_mode to 1 in Danger's devicetree.cb and saw
dev mode screen output to HDMI display.
