Revert driver core: fix passing platform_data

Browse source 
This reverts commit ce21c7bcd7:
	We will remove platform_data field from struct device until
	all platform devices pass its specific data from platfom_device
	and all platform drivers use platform specific data passed by
	platform_device->platform_data. This kind of conversion will
	need a long time, for thousands of files is affected.

	To make the conversion easily, we allow platform specific data
	passed by struct device or struct platform_device and platform
	driver may use it from struct device or struct platform_device.

As we really don't want to do this at all.
