vboot: remove OPROM-related code
As of CL:1605641, vboot2 code should be used for setting and checking display init state. Remove all vboot1 OPROM-related code, and use the vboot2 display init code which has already been added in previous commits. coreboot should not be reading vboot NVRAM flags directly. Remove the function vboot_wants_oprom(), and instead rely on display_init_required(), which uses the VBOOT_WD_FLAG_DISPLAY_INIT value stored in vboot_working_data.flags, initialized during verstage. Note that this means in the case of CONFIG_VBOOT=y, the return value of display_init_required() can only be trusted after verstage has been executed. This should not be a problem assuming that all display initialization occurs in ramstage.
