Display Port (DP) has own dma driver that's why add this skeleton driver only for handling power domain setting and send configuration object to PMUFW to enable it.

Enable driver model for DMA. DMA engines can do
|
|
asynchronous data transfers without involving the host
|
|
CPU. Currently, this framework can be used to offload
|
|
memory copies to and from devices like qspi, ethernet
|
|
etc Drivers provide methods to access the DMA devices
|
|
buses that is used to transfer data to and from memory.
|
|
The uclass interface is defined in include/dma.h.

Enable channels support for DMA. Some DMA controllers have multiple

channels which can either transfer data to/from different devices.

Enable some legacy DMA code for lpc32xx. It provides some direct

functions likes lpc32xx_dma_wait_status() which can be called from

other code.

This should be converted to use driver model and UCLASS_DMA.
