loraspi: add lorapi_rfm98w profile for SX1278/RFM98W at 433 MHz 
The Digital Concepts LoRa-Pi hat ships in two variants: RFM95W (SX1276,
868/915 MHz) and RFM98W (SX1278, 433 MHz).  SX1276 and SX1278 are
register-identical; add a lorapi_rfm98w alias with the same pin
assignments so users can select the correct name for their module.
