ARM: qemu: support for state & env via DT overlay
Add support for state and barebox environment by applying an overlay on
top of the qemu generated device tree. If qemu is used with a persistent
flash partition, this allows usage of environments and state across qemu
reboots.
Simple testing can be performed by starting with
qemu-system-arm -m 256M -M virt -kernel images/barebox-dt-2nd.img -nographic
Storing data, changing into the qemu console via Ctrl-A Ctrl-C, issuing
'system_reset' and Ctrl-A Ctrl-C to get back into the barebox console.
