drm/print: add drm_dbg_printer() for drm device specific printer
We've lacked a device specific debug printer. Add one. Take category into account too. __builtin_return_address(0) is inaccurate here, so don't use it. If necessary, we can later pass __func__ to drm_dbg_printer() by wrapping it inside a macro.
