This patch enables networking support for TI's J721e SoC. Patch 1 adds a new interface to DMA uclass to get channel specific private/configuration data. Patch 2 to 4 use this interface to pass data from J721e's UDMA driver to CPSW ethernet driver. Last two patches add DMA and CPSW DT nodes and configs.
Depends on [1] for ethernet to work
