[U-Boot] [PATCH v2] efi: Update README.efi to clarify build and test instructions

[Stoppa, Igor]

Hello Bin,
a couple more of last-minute comments below:

Since qemu-x86_defconfig was an example, maybe this could be written as:

make <selected defconfig, i.e. qemu-x86_defconfig>
change EFI settings according to what described above
make

Would it be worth mentioning somewhere here that the
payload/application obtained out of the build process should be
deployed as
/efi/boot/bootx64.efi or /efi/boot/bootia32.efi, to make it load
automatically from the BIOS?

Strictly speaking this is not U-Boot business, but it might simplify
the life of the users to state it explicitly.

One other thing that I haven't fully investigated yet (so maybe it's
already explained elsewhere) is: after the application/payload is
built for x86 EFI,
how to deal with the environment partition?

If this is the end of the x86/efi specific documentation and one
should refer to something else, it would be good to have a
link/reference to the next doc.
