efi_loader: Add "bootefi" command
In order to execute an EFI application, we need to bridge the gap between
U-Boot's notion of executing images and EFI's notion of doing the same.
The best path forward IMHO here is to stick completely to the way U-Boot
deals with payloads. You manually load them using whatever method to RAM
and then have a simple boot command to execute them. So in our case, you
would do
# load mmc 0:1 $loadaddr grub.efi
# bootefi $loadaddr
which then gets you into a grub shell. Fdt information known to U-boot
via the fdt addr command is also passed to the EFI payload.
