2.3.2 MMIO: Upgrade registers layout to version 2

This patch addresses VIRTIO-44:

* Clarifies MagicValue content
* Bumps up the Version value to 2
* Removes paged-based addressing and replaces it
  with 64 bit addresses
* Replaces implicit queue organisation (based
  on alignment size) with explicit desc/avail/used
  addreses (based on original MST's patch, see
  VIRTIO-41)
* Introduces explicit protocol for queue
  enabling (based on original MST's idea)
  and disabling
* Defines driver's reaction to an invalid
  device ID (0x0).
