of/device: Rework to use common platform_device_alloc() for allocating devices
The current code allocates and manages platform_devices created from the device tree manually. It also uses an unsafe shortcut for allocating the platform_device and the resource table at the same time. (which I added in the last rework; sorry). This patch refactors the code to use platform_device_alloc() for allocating new devices. This reduces the amount of custom code implemented by of_platform, eliminates the unsafe alloc trick, and has the side benefit of letting the platform_bus code manage freeing the device data and resources when the device is freed.
