Feature: sysfs-dma

Feature adds autodetection support for DMA-related helper devices referenced from sysfs.

It follows dma:* links below the detected device and recursively guesses the dependencies of those DMA endpoints. This is mainly useful on platforms where DMA wiring is exposed through auxiliary sysfs links rather than stable public device nodes.
