The ksz8795 driver is using port_cnt differently to the other microchip
DSA drivers. It sets it to the external physical port count, than the
whole port count (including the cpu port). This patch is aligning the
variables purpose with the other microchip drivers.

v1 -> v2: - improved comment in port_cnt assignment, rather than removing it
