src/security/vboot: Add config option to skip display init

This config option, when set, will allow the platform to skip display
initialization in normal (non-developer, non-recovery) mode boot for
chromeos. When not set, it allows the platform to initialize the
display in non-chromeos vboot mode.

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.
