Add a code to create CMA region from

Or do you think the problem is more likely to be clock-related?
Hard to say right now, but at least we need to test a bit more our
solutions with different initial clocks configuration.

regions without 'reusable' property and CMA is used only for handling
'shared-dma-pool' regions with 'reusable' property.

Summary:

This patch adds support for dynamically allocated reserved memory regions
declared in device tree. Such regions are defined by 'size', 'alignment'
and 'alloc-ranges' properties.
Based on previous code provided by Josh Cartwright

Add support for custom reserved memory drivers. Call their init() function
for each reserved region and prepare for using operations provided by them
with by the reserved_mem->ops array.
