Enable this so that EFI applications (notably grub) can be run under U-Boot
on x86 platforms.
At present the 'hello world' EFI application is not supported for the
qemu-x86_efi_payload64 board. That board builds a payload consisting of a
64-bit header and a 32-bit U-Boot, which is incompatible with the way the
EFI loader builds its EFI application. The following error is obtained:
x86_64-linux-ld.bfd: i386 architecture of input file
`lib/efi_loader/helloworld.o' is incompatible with i386:x86-64 output
This could be corrected with additional Makefile rules. For now, this
feature is disabled for that board.

This line is shown as
depends on (ARM64 ||\302\240ARM) && OF_LIBFDT
on my Emacs. Use ASCII characters only.
Assuming it is (ARM64 || ARM), remove the redundancy.
Unlike Linux, CONFIG_ARM includes CONFIG_ARM64 in U-Boot.

Some hardware that is supported by U-Boot can not handle DMA above 32bits.
For these systems, we need to come up with a way to expose the disk interface
in a safe way.
This patch implements EFI specific bounce buffers. For non-EFI cases, this
apparently was no issue so far, since we can just define our environment
variables conveniently.

Now that we have all the bits and pieces ready for EFI payload loading
support, hook them up in Makefiles and KConfigs so that we can build.
