Subject: [PATCH net-next 1/4] net: dsa: b53: Include all ports in "enabled_ports"

From: Rafał Miłecki <rafal@...ecki.pl>

Make "enabled_ports" bitfield contain all available switch ports
including a CPU port. This way there is no need for fixup during
initialization.

For BCM53010, BCM53018 and BCM53019 include also other available ports.
