net: dsa: b53: Disable all ports on setup
A b53 device may configured through an external EEPROM like the switch
device on the Lamobo R1 router board. The configuration of a port may
therefore differ from the reset configuration of the switch.
The switch configuration reported by the DSA subsystem is different until
the port is configured by DSA i.e. a port can be active, while the DSA
subsystem reports the port is inactive. Disable all ports and not only
the unused ones to put all ports into a well defined state.
