Driver core: Make platform_device_add_data accept a const pointer

platform_device_add_data() makes a copy of the data that is given to it, and thus the parameter can be const. This removes a warning when data from get_property() on powerpc is handed to platform_device_add_data(), as get_property() returns a const pointer.
