All of the device init and device driver interaction with omap_device is done using platform_device pointers. To make this more explicit, have omap_device return a platform_device pointer instead of an omap_device pointer. All current users of the omap_device pointer were only using it to get at the platform_device pointer or struct device pointer, so fixing all of the users was trivial. This also makes it more difficult for device init code to directly access members of struct omap_device, and allows for easier changing of omap_device internals.
