Adrian Chadd 0f0eebe793 Initial AR9485/AR933x 1x1 LNA diversity work.
* Add the LNA configuration table entries for AR933x/AR9485
* Add a chip-dependent LNA signal level delta in the startup path
* Add a TODO list for the stuff I haven't yet ported over but
  I haven't.

Tested:

* AR9462 with LNA diversity enabled
