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
DPlus compliant 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.

These controllers provide DMA capabilities for a variety of on-chip
devices such as SSC, HSNAND and GSWIP.

-------------
Future Plans:
-------------
LGM SOC also supports Hardware Memory Copy engine.
The role of the HW Memory copy engine is to offload memory copy operations
from the CPU.
