4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Aaro Koskinen <aaro.koskinen@iki.fi>
commit c0fae7e2452b90c31edd2d25eb3baf0c76b400ca upstream.
The maximum number of interfaces is returned by cvmx_helper_get_number_of_interfaces(), and the value is used to access interface_port_count[]. When CN68XX support was added, we forgot to increase the array size. Fix that.
