Subject: [PATCH lora-next 2/4] dt-bindings: lora: sx125x: add basic documentation

The sx125x family are IQ radio transceivers from Semtech configured over
SPI, they are typically connected to an sx130x series concentrator however
may be connected to a host directly.

Required properties include the radio number of the host or concentrator
bus.
