The KSZ9477 and KSZ8795 use the port_cnt field differently: For the KSZ9477, it includes the CPU port(s), while for the KSZ8795, it doesn't.
It would be a good cleanup to make the handling of both drivers match, but as a first step, fix the recently broken assignment of num_ports in the KSZ8795 driver (which completely broke probing, as the CPU port index was always failing the num_ports check).
