src/security/vboot: Add option to skip display init with vboot 2.0
This config option, when set, will allow the platform to skip display
initialization in normal (non-developer, non-recovery) mode. This allows
platforms that do not implement firmware UI in normal mode to skip the
display init in firmware.
TEST=Set option CONFIG_VBOOT and clear CONFIG_VBOOT_MAY_SKIP_DISPLAY_INIT
and the display should initialize in ramstage when platform boots. Set
CONFIG_VBOOT and set CONFIG_VBOOT_MAY_SKIP_DISPLAY_INIT and the display
initialization should be skipped in coreboot.
