Character driver for the Semtech SX1301, the baseband processor of a LoRaWAN
gateway, and the two SX125x radios it drives. Received packets come from
read(), downlinks go to write(), and the channel plan, the start and the stop
are ioctls.
The interface is device independent, in nuttx/wireless/lpwan/lora_gw.h with
the commands in the common WLIOC_GW_* space, so another concentrator driver
can implement it and the same application drive it.
Adds a lorawan_gw configuration for the Nucleo F746ZG with a shield of the
LRWAN_GS_HF1 family. Off by default (LPWAN_SX1301).

This commit moves sx127x Kconfig to lpwan/sx127x/ to follow the
same logic used by sx126x and adds the configuration to support
different bitrate (the default 4800 is fine tuned for LORA).

radio transceivers. This initial support includes transmit and receive
functionality and configuration and reading of radio parameters like
frequency and bandwidth.

[Experimental]
This adds a driver for the SX126x (SX1261 and SX1262) LoRa chips.
All functions and definitions are coming directly from the DS SX1261-2 V2.1 datasheet.

SX127X improvements
drivers/wireless/lpwan/sx127x/sx127x: add TX power configuration
drivers/wireless/lpwan/sx127x/sx127x: discard RX packets with unsupported length
drivers/wireless/lpwan/sx127x/sx127x: refactor some logic
drivers/wireless/lpwan/Kconfig: move some hardcoded sx127x configuration to Kconfig
drivers/wireless/lpwan/Kconfig: remove EXPERIMENTAL flag
configs/b-l072z-lrwan1/sx127x: board-specific sx127x configuration
configs/nucleo-f091rc/sx127x: board-specific sx127x configuration
configs/nucleo-l073rz/sx127x: board-specific sx127x configuration
LORA and FSK look fine but there is something missing for OOK and communication is not working yet.
