The implementation of the board support routines is shared between all LoRa drivers that use LoRaMAC-Node. Move them from the SX1276 implementation to a separate source file to facilitate reuse. Make this source file conditional on CONFIG_HAS_SEMTECH_RADIO_DRIVERS since it will be used by all LoRaMAC-Node-based drivers. Signed-off-by: Andreas Sandberg <andreas@sandberg.pp.se>
