Stacey Sheldon 740b5f1584 rcvr: convert PWM, PPM, SBUS and Spektrum to use PIOS_RCVR
All receivers now fall under the same driver API provided
by pios_rcvr.c.

This is part of a larger sequence of commits that will
switch the receiver selection over to boot time dynamic
configuration via UAVObjects.
