driver core: move platform_data into platform_device

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.
