    rambi: Fix eDP panel functionality
    
    For some mysterious reason GPIO_S0_NC22 is making the eDP panel
    go entirely white when it is configured with internal pullup.
    Since these (supposedly XDP related) pins are unknown functionality
    lets set them to GPIO_DEFAULT instead of GPIO_NC.
    
    Additionally the VBIOS is being changed to issue int15 callback
    to determine the boot graphics device.  If we list both LFP and EFP
    then the dev/rec screens will show on the panel when HDMI is not
    attached and otherwise will display on HDMI.
    
    BUG=chrome-os-partner:23507
    BRANCH=rambi
    TEST=build and boot on rambi, see firmware/kernel screens on the panel
    when HDMI is not attached, and firmware screens on the panel and
    kernel screens on both when HDMI is attached.
