SPI displays do not work with mpd_oled on the Raspberry PI 5.

This was reported on the Moode forum

Unfortunately, it looks like there is no easy fix for this, as the BCM 2835 library hasn't been (and may not ever be) updated to support the Pi 5

In which case, some options are

a) The current version of mpd_oled won't be updated to support the Pi 5 (I don't like this option)

b) I could add some custom SPI functions that use the linux SPI devices.

c) I could tidy up the development "proof of concept" version ( https://github.com/antiprism/mpd_oled_dev ), which only uses linux devices for communication.
