device property: Add const qualifier to device_get_match_data() parameter

commit aade55c86033bee868a93e4bf3843c9c99e84526 upstream.

Add const qualifier to the device_get_match_data() parameter.
Some of the future users may utilize this function without
forcing the type.

All the same, dev_fwnode() may be used with a const qualifier.
