b53: allow ports with higher numbers than CPU port
Our code was assuming CPU port uses the highest number. My BCM53573 device has eth0 connected to port 8 and eth1 connected to port 5. While working on support for it I tried to: 1) Enable all ports (including port 8) 2) Set CPU port to 5 I noticed port 8 is not accessible anymore. It was just a development process but it seems like something worth fixing anyway. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Acked-by: Jonas Gorski <jonas.gorski@gmail.com>
