Right now the only way to get the SPI pumping thread bumped up to realtime priority is for the controller to request it. However it may be that the controller works fine with the normal priority but communication to a particular SPI device on the bus needs realtime priority. Let's add a way for devices to request realtime priority when they set themselves up. NOTE: this will just affect the priority of transfers that end up on the SPI core's pumping thread. In many cases transfers happen in the context of the caller so if you need realtime priority for all transfers you should ensure the calling context is also realtime priority.
