This patch adds a new boot firmware to buildroot for building the zynqmp pmufw.
It requires the toolchain-bare-metal package that includes a bare-metal
binutils, gcc and newlib which can be built for the microblaze architecture.

Signed-off-by: Neal Frager <neal.frager@amd.com>
---
V1->V2:
 - builds a bare-metal gcc toolchain instead of requiring an external
   microblaze toolchain
V2->V3:
 - corrected custom cflags option
 - added support for xilinx_v2022.2 version
 - added zynqmp-firmware.hash
V3->V4:
 - no changes
V4->V5:
 - reduced all lines to <80 chars
V5->V6:
 - migrated to toolchain-bare-metal-buildroot
V6->V7:
 - removed patch numbers
 - changed dependency to toolchain-bare-metal-buildroot
 - removed hash since version is configurable
V7->V9:
 - no changes
V9->V10:
 - removed patches for supporting versions older than xilinx_v2023.2
V10-V11:
 - set default BR2_TOOLCHAIN_BARE_METAL_BUILDROOT_ARCH to
   "microblazeel-xilinx-elf" to avoid stand-alone build failure
