arm-autonomy: Fix circle dependency in xen-dtb

Solve circle dependency in xen-devicetree when initramfs is activated as
compile depends on kernel:do_deploy and xen-devicetree is needed to
create the arm-autonomy-host-image-minimal.
Move all actions in do_deploy so that only do_deploy depends on the
kernel do_deploy.
