video: simplefb: Parse memory region from memory-region property
Linux' simplefb driver allows setting the memory-region property to a
phandle to a node that describes the memory to be used for the
framebuffer. If it is present, it will override the "reg" property.
This adds support for parsing the property and prefers it if present.
