sdma: Added udev rule and script for sdma firmware
At the moment, the sdma firmware is loaded via a service. This is already a workaround, because including the firmware directly taints the kernel. However, the service approach isn't flexible when introducing new processors. We now load the sdma firmware via a udev rule, that is run when the dma controllers are added.
