drivers: dma-contiguous: add initialization from device tree
Add device tree support for contiguous memory regions defined in device tree. Initialization is done in 2 steps. First, the contiguous memory is reserved, what happens very early, when only flattened device tree is available. Then on device initialization the corresponding cma regions are assigned to device structures.
