7bda3b7c8b wireless/lpwan/sx127x: fix the frequency step, the band and the LoRa only build
- The frequency step was truncated to 61 Hz, while it is FXOSC/(2**19),
  about 61.035 Hz.  The error puts a 915 MHz channel more than 500 kHz away
  from the requested frequency, outside its own bandwidth.

- The low or high frequency front end was left at its reset value, so a board
  wired for 868 or 915 MHz neither transmitted nor received.

- sx127x_rx_watchdog() is only used by the FSK and OOK path but was compiled
  whenever receive support was on, so a LoRa only configuration failed to
  build with -Werror.  nrf52840-dk:sx127x is such a configuration.

Adds the sync word, the default bandwidth and the default spreading factor as
configuration options, all defaulting to the previous behaviour, and a page
for the driver under components/drivers.

f37bc4546e wireless/lpwan: add SX1301 LoRa concentrator driver
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).
