Revert driver core: move platform_data into platform_device

This reverts commit 006f4571a15fae3a0575f2a0f9e9b63b3d1012f8:

	This patch moves platform_data from struct device into
	struct platform_device, based on the two ideas:

	1. Now all platform_driver is registered by platform_driver_register,
	   which makes probe()/release()/... of platform_driver passed parameter
	   of platform_device *, so platform driver can get platform_data from
	   platform_device;

	2. Other kind of devices do not need to use platform_data, we can
	   decrease size of device if moving it to platform_device.

	Taking into consideration of thousands of files to be fixed and they
	can't be finished in one night(maybe it will take a long time), so we
	keep platform_data in device to allow two kind of cases coexist until
	all platform devices pass its platfrom data from
	platform_device->platform_data.

	All patches to do this kind of conversion are welcome.

As we don't really want to do it, it was a bad idea.
