[DRIVER MODEL] Add platform_driver
Introduce struct platform_driver. This allows the platform device driver methods to be passed a platform_device structure instead of instead of a plain device structure, and therefore requiring casting in every platform driver. We introduce this in such a way that any existing platform drivers registered directly via driver_register continue to work as before, thereby allowing a gradual conversion to the new platform_driver methods.
