drm: Pass pointers to virt_to_page()
Most architectures define virt_to_page() as a macro that casts its argument such that an argument of type unsigned long will be accepted without complaint. However, the proper type is void *, and passing unsigned long results in a warning on MIPS. Compile-tested only.
