    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.
