We should not try to directly access the keyboard when running as an EFI app. Disable CONFIG_I8042_KEYB option to prevent that. Signed-off-by: Simon Glass <sjg@chromium.org>

For now this is not used, pending further work on teasing this

This enables mouse support when U-Boot is running as an EFI

mouse input from the underlying EFI firmware. This is useful

when U-Boot is used as an EFI boot manager or application.
