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.

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/
