pin mapping, duckeron

- updated a3pro pwm pin mapping to match comment block
- updated nanowii pin mapping PE6 == ailr_in instead of aux2_in
- duckeron brake starts from 1100us instead of 1000us
- minor cleanups with wing_mode setting, added catchall incase it is still invalid after all the per-device checks.
oops, fixed error in a3pro for spektrum/sbus and wing_modes
