This jumps to test code which can call directly into the EFI support. It
does not need a separate image so it is easy to write tests with it.
This test can be executed without causing problems to the run-time
environemnt (e.g. U-Boot does not need to reboot afterwards).
For now the test just outputs a message. To try it:
./sandbox/u-boot -c "bootefi test"
