[stm32f4_spektrum] Fixes the additional glitch pulse.

Browse Source 
If you set the alternate function before setting the pin to input AF.
The GPIO will pull down the line down very briefly. This will cause an
additional pulse to be detected by a spektrum satellite if it is being
reconfigured as a UART RX after sending bind mode pulses.

closes #1090 and fixes #780
