CC3D - don't share timer between PPM capture and motor output

Browse source 
A periodic glitch happens on AUX channels when using OneShot on CC3D,
especially with faster update loops. This is caused by a race condition
while forcing timer overflows and sharing the timer for PPM capture.
It causes the craft the fall out of the sky when using a switch to arm.

* Remap PPM in from S1_IN to S6_IN
* Remap RSSI_ADC from S6_IN to S3_IN
* Block PWM12/S6_OUT from being used with Oneshot/brushed motors so
TIM2 (PPM_IN timer) doesn't change prescaler or is manually overflowed
* Allow only one feature out of SOFTSERIAL/RSSI_ADC/SONAR, since they
will now share the same pin
* Update docs to reflect port changes and restrictions

This fixes cleanflight/cleanflight#1748,
