-- SPI: Cache the SPI device in the communication interface. Architecturally, this makes a
-  lot more sense because each ComIF should be responsible for one SPI bus.
-- SPI: Move the empty transfer to update the line polarity to separate function. This means
-  it is not automatically called when calling the setter function for SPI speed and mode.
-  The user should call this function after locking the CS mutex if multiple SPI devices with
-  differing speeds and modes are attached to one bus.
