Work in progress. In testing using bluetooth on uart2 and uart1
connected to configurator it was observed that there is corrupted
responses being sent via uart2 - ez-gui shows some garbled data for the
box names. updates appear sluggish in ez-gui but some correct data is
getting through.
Enabled with:
set serial_port_2_scenario = 8

This has highlighted that the existing codebase is quite targeted
towards systems that use USART1 and 2. Annoyingly the inverter is on
USART1 and the sbus code requires callbacks so still won't work yet.
