In order to add bcm6348-enet support, dma-uclass must be extended to support dma channels and reworked to operate like the other dm uclass (clk, reset...).
This is a RFC, so please give you feedback on the things that I should fix or rework.
v2: Introduce changes reported by Vignesh: - Respect current dma implementation. - Let dma_memcpy find a compatible dma device. Other changes: - Fix bcm6348-iudma rx burst config.
