[Buildroot] [PATCH v2 0/6] Introduce EDK2 firmware builds

Hi all,

Here is a more simplified and somewhat cleaner revision of the series
introducing the ability to build EDK2 UEFI firmware in Buildroot.

This series is introducing the EDK2 bootloader package which can build
firmware for five different platforms, targeting both x86-64 and AArch64.

 * QEMU x86-64 pc machine
 * QEMU aarch64 virt machine, booting directly from flash
 * QEMU aarch64 virt machine, booting via kernel protocol
 * QEMU aarch64 sbsa-ref machine
 * ARM FVP vexpress machine

The EDK2 build system is very particular and includes different
dependencies and a lot of custom scripting, which has lead to these design
decisions when building these Buildroot packages:

 * EDK2 needs to rely on Git submodules because its dependencies are not
   easy to build separately
 * Each platform is a specific configuration option (instead of a string)
   because they require slightly different packages etc.

To keep it simple, this series no longer introduce the concept of "SBBR"
Although, the firmware build with ATF + EDK2 + ACPI is mostly compliant
with SBBR.
