xen: enable qemuboot for arm32

Add required variables to generate a qemuboot devicetree for qemuarm.
With this change, Xen and dom0 can be started using runqemu.

Xen is started using qemu kernel argument and the devicetree is modified
to properly boot dom0 (which is loaded in memory).
This is using the same system as qemuarm64.

At this stage dom0 is hanging on PCI device scanning.

This patch is also using qemuarm64 as machine for arm64 bit instead of
aarch64 to allow adding support for other machine (an example a Xilinx
board that can be emulated with using an other xen machine).
