Update gpio/ledring drivers so they do not include "board.h". It is now

clear what all gpio/ledring drivers need to compile and what was
unnecessarily included before.
 
In attempting this it was clear that ledring had a dependency on the
multiwii code, this was removed by passing the led status update method
the values it needs.

It also turned out that the ROLL/PITCH defines were coming from
rc_alias_e and much unrelated code is coupled to these defines.  This
commit also includes some cleanups relating to that problem.
