    driver core: move platform_data into platform_device · 006f4571

    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.
