A global flag oprom_is_loaded was used to indicate to U-boot that VGA option ROM was loaded and run, or that native VGA init was completed on GMA device. Implement this feature without dependency to CHROMEOS option and replace use of global variable oprom_is_loaded with call to gfx_get_init_done().
