dmaengine: Add Intel LGM SoC DMA support. 



Add DMA controller driver for Lightning Mountain (LGM) family of SoCs.

The main function of the DMA controller is the transfer of data from/to any
peripheral to/from the memory. A memory to memory copy capability can also
be configured.

This ldma driver is used for configure the device and channnels for data
and control paths.
