For preparing the radio drivers (specifically SX1276) for LoRaWAN
support, let's add missing function definitions and callbacks required
by the stack.

Since TimerIrqHandler() API does SPI transactions, it is not advised to
call from an IRQ context. Hence, offload it to a work queue.

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.
