Almost every platform_driver does the three steps get_resource, request_mem_region, ioremap. This does not only lead to a lot of code duplication, but also a huge number of similar error strings and inconsistent error codes on failure. So, introduce a helper function which simplifies remapping a resource and make it hard to do something wrong and add documentation for it.
