* Fix wio-tracker-1110 lora radio reset GPIO assignment This fixes flaky lora radio init on this board. * No need to keep lr11x0 radio config during sleep anymore, also stop TCXO I think the problem (at least on the board I'm using for power testing a wio tracker 1110) was that actually the RESET GPIO was not correct for the radio. This led to the radio not being properly reinited after exiting sleep mode. Now that the GPIO is fixed I can enter deep sleep (fully shutting down radio) and then later when the CPU resets, it can successfully init the radio and send packets. After this seeming success, I also turned off the TCXO during sleep and that worked as well.
