Hook up the new U-Boot recipe, provide new wks files and disable the
watchdog for EFI Boot Guard - that's all what's need to allow offering
SWUpdate and secure boot for the QEMU arm64 target.

QEMU currently does not provide a watchdog for the virt machine which we
plan to use. A patch to change this has been sent, but for now we will
have to live without one.
