SBUS Issue
----------
When the dedicated SBUS output port is used on boards with a IOMCU
(such as Hex Cube or Holybro Duandal) then SBUS would be interrupted
on loss of RC input. The problem was that the same UART was used for
both SBUS output and RC input. When RC input is lost the RC protocol
system starts searching for a receiver, which involves changing
baudrate on that UART. That baudrate change affected SBUS output. This
means if your aircraft depends on SBUS output to fly and you get an RC
failsafe you risk losing RC outputs. The fix is to not change
baudrates on that port when SBUS output is enabled (which means
protocols like FPort can't be used when IOMCU SBUS output is used).
