The devm_* functions eliminate the need for manual resource releasing and simplify error handling. Resources allocated by devm_* are freed automatically on driver detach.

Factors out some boilerplate code for drivers doing the default thing for platform driver registration. Drivers using platform_driver_probe or an initcall other than module_init can't be converted.

Add support for Intel MSIC chip found on Intel Medfield platforms. This chip embeds several subdevices: audio, ADC, GPIO, power button, etc. The driver creates platform device for each subdevice. We also provide an MSIC register access API which should replace the more generic SCU IPC interface currently used. Existing drivers can choose whether they convert to this new API or stick with the SCU IPC interface.
