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.
