Subject: [PATCH v1 1/1] device property: Add const qualifier to device_get_match_data() parameter

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.
