net: lora: Add Semtech SX1301
The Semtech SX1301 was the first multi-channel LoRa "concentrator".
It uses a SPI interface to the host as well as a dual SPI interface to
its radios. These two have been implemented as spi_controller, so that
the Device Tree can specify whether the respective module uses two
SX1257, two SX1255 or a combination of these or some unforeseen chipset.
This implementation is the most recent - initialization is not yet
complete, it will need to load firmware into the two on-chip MCUs.
Unfortunately there is no full datasheet with register descriptions,
only a BSD-licensed userspace HAL implementation using spidev devices.
Therefore some register names are unknown.
