New since v1: - expose control register size (suggested by Marc MarĂ)
- leaving out _UID and _STA fields (thanks Shannon & Igor) - using "QEMU0002" as the value of _HID (thanks Michael) - added documentation blurb to docs/specs/fw_cfg.txt (mainly to record usage of the "QEMU0002" string with fw_cfg).
