From: Sven Van Asbroeck <thesve...@gmail.com>
On the ksz8795, if the devicetree contains a cpu node,
devicetree parsing fails and the whole driver errors out.
Fix the devicetree parsing code by making it use the
correct number of ports.
Fixes: 912aae27c6af ("net: dsa: microchip: really look for phy-mode in port
nodes")
