Jorge Guzman 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.
