security/vboot: Add config option to always enable the display
In order to always show the bootlogo very early in coreboot we need the
option to always enable the display when VBOOT is enabled.
To do this a config option is added to make sure this functionality can
be provided without interfering with systems that require the standard
VBOOT display handing.
BUG=N/A
TEST=tested on facebook fbg1701.
