dma_slave_caps is very important to the generic layers that might interact with dmaengine, such as ASoC. Unfortunately, it has been added as yet another dma_device callback, and most of the existing drivers haven't implemented it, reducing its reliability. Introduce a generic behaviour to implement this, that rely on both the split of device_control to derive which functions are supported and on new variables to be set in the dma_device structure. These variables holds what used to be the capabilities, that were set per-channel. However, this proved to be a bit overkill, since every driver filling these so far were hardcoding it, disregarding which channel was actually given.
