vboot: communicate display requirements with vb2api_fw_phase1
Input: tell vb2api_fw_phase1 if display unconditionally available
Output: vb2api_fw_phase1 may request coreboot to initialize
display, if needed based on some internal request
Move setting the VBOOT_FLAG_DISPLAY_REQUESTED flag into
verstage_main.
