Allow displaying the U-Boot banner on a video display
At present the U-Boot banner is only displayed on the serial console. If
this is not visible to the user, the banner does not show. Some devices
have a video display which can usefully display this information.
Add a banner which is printed after relocation only on non-serial devices
if CONFIG_DISPLAY_BOARDINFO_LATE is defined.
