drivers/xgi/z9s: Port Linux framebuffer initialization to coreboot

Add native XGI Z9s framebuffer support to coreboot
    XGI initialization code largely taken from Linux 3.18.5

TEST: Booted KFSN4-DRE with XGI Volari Z9s into SeaBIOS
    with SeaVGABIOS enabled.  Text appeared correctly on screen
    and interaction with graphical comboot menu was successful.
    However, Linux cleared the framebuffer on boot, rendering the
    screen useless until Linux loaded its native xgifb driver.
