To enable to build as module, convert the separate platform driver into a single module_platform_driver with the data selection done via compatible string and of_match. The separate of_match tables are also combined into a single table to avoid the multiple calls to of_match_node() Since all modern TI platforms using this are DT enabled, the removal of separate platform_drivers shoul should nave no functional change.
