drm/mcde: Fix DSI transfers
There were bugs in the DSI transfer (read and write) function as it was only tested with displays ever needing a single byte to be written. Fixed it up and tested so we can now write messages of up to 16 bytes and read up to 4 bytes from the display. Tested with a Sony ACX424AKP display: this display now self- identifies and can control backlight in command mode.
