Hi Jassi,

Here is the updated version based on your suggestions.

I feel bad that I haven't implemented the single-word protocol as a
special case of multi-word one in the earlier attempt. Perhaps I was too
consumed by the terminology used by the ARM folks in the previous
version of the driver and the reference manual of the controller :)

V1/V4->V5

- The binding patch already had 4 versions, while the driver had only 1.
  To send everything together, I had to bump the entire thing to V5.

- Removed single-word and multi-word protocols and introduced
  data-transfer protocol which works with 1 or more windows.

- Moved register names to small case.

Rob, I have kept your Reviewed-by tag as is, please let me know if you
would like to revoke it.
