Add multiple SPI devices for Radio, Display, and Touchscreen (#3638) 
This changeset gives us the ability to specify a separate SPI device for the LoRa, Display, and Touchscreen. The changes in Portduino also add support for specifying a new SPI speed for each transaction. All together, this means that we can let the Linux OS manage the CS lines, and also get much faster SPI speeds, leading to better framerates.

* Add multiple SPI devices to put Radio, Display, and Touchscreen on each their own
