When troubleshooting RF applications, one of the most common approaches is to
ensure that both sides of the communication path are using the same 
configuration such as bit rate, frequency deviation, encryption key, sync words
and so on.

The existing driver implementation doesn't allow the user to see which values
have been configured onto the uC which makes trobleshooting more painful than
it needs to be.

This patchset adds debugfs interface to this driver and exposes a read-only
access to uC reg values to address that problem.
