This probe function is only called if the device is backed by a DT node,
so switch this call to of_device_get_match_data() to reduce code size
and simplify a bit. This also avoids needing to reference a potentially
undefined variable because of_device_get_match_data() doesn't need to
know anything beyond the struct device to find the match table.
