dt: introduce of_get_child_by_name to get child node by name
This patch introduces of_get_child_by_name function to get a child node by its name in a given parent node. Without this patch each driver code has to iterate the parent and do a string compare, However having of_get_child_by_name libary function would avoid code duplication, errors and is more convenient.
