Board support: RAK3401+RAK13302 1-watt (#8140)

* Add RAK3401 variant files

* Add SPI configuration for RAK3401 and RAK13302 variants

* Refactor SPI pin configuration and clean up variant definitions for RAK3401

* Add TX_GAIN_LORA for RAK13302 Power Amp

* Fix merge

+; Note: as of 6/2013 the serial/bootloader based programming takes approximately 30 seconds
+;upload_protocol = jlink
+
+; Allows programming and debug via the RAK NanoDAP as the default debugger tool for the RAK4631 (it is only $10!)
+; programming time is about the same as the bootloader version.
