The Xen hypervisor built for Arm 32-bit targets can be launched with
runqemu by providing a u-boot script and configuration for Qemu, which
enables interactive testing of Xen images.
Add qemuboot-xen-u-boot.bbclass to add a new bitbake task for generating
the u-boot script. Since this increases the number of qemuboot-specific
classes that are inherited by the xen-image-minimal recipe, change the
inherit of all of these to only apply to qemu machines with the qemuall
override.
Update qemuboot-xen-defaults.bbclass to supply working default
parameters for the qemuarm machine needed to boot successfully in
testing. Also change all the arch-specific variable overrides into
narrower qemu platform overrides instead to avoid unnecessary
interactions with other Arm platform machines.

The Xen hypervisor built for Arm 64-bit targets can be launched with
runqemu by providing a Device Tree binary and configuration for Qemu,
which enables interactive testing of Xen images.
Add qemuboot-xen-dtb.bbclass to add a new bitbake task for generating
the dtb file by using lopper on a device tree produced by Qemu.
Add qemuboot-xen-defaults.bbclass to supply working default parameters
for the qemuarm64 machine and general support for qemuboot for Xen,
and adjust the defaults as needed to boot successfully in testing.
