- Add support for the RDC 1010 variant
- Rework the core library to have a read_id method. This allows the hacky
  bits of it821x to go and prepares us for pata_hd
- Switch from WARN to BUG in ata_id_string as it will reboot if you get
  it wrong so WARN won't be seen
- Allow the issue of command 0xFC on the 821x. This is needed to query
  rebuild status.
- Tidy up printk formatting
- Do more ident rewriting on RAID volumes to handle firmware provided
  ident data which is rather wonky
- Report the firmware revision and device layout in RAID mode
- Don't try and disable raid on the 8211 or RDC - they don't have the
  relevant bits
