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.
