Recent Progress - Stable Spektrum satellite receiver

My Lisa/m always crashed when I tried to bind my radio.
I recently found the solution. The interrupt handler for the URART which the second Satellite is connected to needs to be overwritten.

<define name="RADIO_CONTROL_SPEKTRUM_SECONDARY_PORT" value="UART5"/>

Felix Reuss came up with a way to make this better

Now only this is needed.

<configure name="USE_SECONDARY_SPEKTRUM_RECEIVER" value="1"/>
