This patch adds basic support for configuring and assisting virtio-mmio based virtio-gpio backend (emualator) which is intended to run out of Qemu and could be run in any domain.
An example of domain configuration for Virtio Gpio: gpio = [ "" ]
Please note, this patch is not enough for virtio-gpio to work on Xen (Arm), as for every Virtio device we need to allocate Virtio MMIO params (IRQ and memory region) and pass them to the backend, also update Guest device-tree. A subsequent patch will add these missing bits. For the current patch, the default "irq" and "base" are just written to the Xenstore.

Most comment on the previous patch would apply to this one as well.
