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.
