crypto: artpec6 - Simplify with of_device_get_match_data()

Driver's probe function matches against driver's of_device_id table, so
of_match_node() can be simplified with of_device_get_match_data().

This requires changing the enum used in the driver match data entries to
non-zero, to be able to recognize error case of
of_device_get_match_data().
