[Buildroot] [PATCH v2 3/6] configs/aarch64_efi_defconfig: build the EDK2 firmware from source

[D. Olsson]

From: Dick Olsson <hi@senzilla.io>

Prior to this, you had to manually download a pre-built EDK2 flash device
image (QEMU_EFI.fd) in order to boot this configuration with QEMU.
Now, the configuration is building EDK2 from source.

 * Explicitly added the default EDK2 platform to defconfig

Should we change this to point to the QEMU_VARS file too as was done
in patch 4 for board/pc/readme.txt ?

Otherwise looks good, I tested it and it works for me.

Yes, that makes sense. I will also switch from using -bios to use the
-pflash interface instead as this is considered better practice when
building the firmware like this (in fact, locally I've been testing with
pflash the whole time).
