dev-arm: Add a MMIO transport interface for VirtIO
The MMIO interface currently only supports a subset of version 0.9.5
of the VirtIO specification. It has the following known limitations:
* The queue size hint (the QUEUE_NUM register) is ignored.
* Queue alignment is assumed to be hard-coded to
VirtQueue::ALIGN_SIZE (4096 bytes).
* Only 4096 byte pages are currently supported.
