uboot-armsr: add support for QEMU armv7/armv8

Browse Source 
Add new package so we can use self-compiled bootloader during QEMU based
testing and development.

Backported fix[1] is needed for EFI boot from virtio devices.

Subject: [PATCH v10 7/9] bootstd: Use blk uclass device numbers to set efi
bootdev
Date: Mon, 24 Apr 2023 13:49:50 +1200
Message-ID:
<20230424134946.v10.7.Ia5f5e39c882ac22b5f71c4d576941b34e868eeba@changeid>
From: Mathew McBride <matt@traverse.com.au>
When loading a file from a block device, efiload_read_file
was using the seq_num of the device (e.g "35" of virtio_blk#35)
instead of the block device id (e.g what you get from running
the corresponding device scan command, like "virtio 0")
This cause EFI booting from these devices to fail as an
invalid device number is passed to blk_get_device_part_str:
Scanning bootdev 'virtio-blk#35.bootdev':
distro_efi_read_bootflow_file start (efi,fname=<NULL>)
distro_efi_read_bootflow_file start (efi,fname=<NULL>)
setting bootdev virtio, 35, efi/boot/bootaa64.efi, 00000000beef9a40, 170800
efi_dp_from_name calling blk_get_device_part_str
dev=virtio devnr=35 path=efi/boot/bootaa64.efi
blk_get_device_part_str (virtio,35)
blk_get_device_by_str (virtio, 35)
** Bad device specification virtio 35 **
Using default device tree: dtb/qemu-arm.dtb
No device tree available
0 efi ready virtio 1 virtio-blk#35.bootdev.par efi/boot/bootaa64.efi
** Booting bootflow 'virtio-blk#35.bootdev.part_1' with efi
blk_get_device_part_str (virtio,0:1)
blk_get_device_by_str (virtio, 0)
No UEFI binary known at beef9a40 (image buf=00000000beef9a40,addr=0000000000000000)
Boot failed (err=-22)

One can find EFI/BIOS binaries from:
- Compile mainline U-Boot for the QEMU ARM virtual machine (qemu_arm_defconfig/qemu_arm64_defconfig)
- From distribution packages (such as qemu-efi-arm and qemu-efi-aarch64 in Debian)
One can obtain other EFI/BIOS binaries from:
- Distribution packages (such as qemu-efi-arm and qemu-efi-aarch64 in Debian)
- Community builds, like retrage/edk2-nightly: https://retrage.github.io/edk2-nightly/
