of/platform: Generalize /reserved-memory handling
By iterating over all /reserved-memory child nodes and match each one to a list of compatibles that we want to treat specially, we can easily extend the list of compatibles to handle - without having to resort to of_platform_populate() that would create unnecessary platform_devices.
