Fix PWM rx 100% CPU load (#5598) 

Previous logic changes were causing the RX task to run every loop for PWM rx leading to 100% CPU load. Reverted PWM processing to be based on a time interval rather than whether new data is available. With PWM we can't differentiate when new data is available as it's a continuous stream.
