Is your feature request related to a problem? Please describe.SBUS and CRSF run at an unconventional baud rate of 100000 and 420000 bps and can not be used with AVR architecture, however IBUS uses a baud rate of 115200, which is supported by the AVR architecture, but the code does not handle that, I request to add this feature for AVR architecture.
Describe the solution you'd like
[x] Handle the case when ARDUINO_ARCH_AVR is defined.
