net: dsa: b53: Fix calculating number of switch ports
It isn't true that CPU port is always the last one. Switches BCM5301x
have 9 ports (port 6 being inactive) and they use port 5 as CPU by
default (depending on design some other may be CPU ports too).
A more reliable way of determining number of ports is to check for the
last set bit in the "enabled_ports" bitfield.
This fixes b53 internal state, it will allow providing accurate info to
the DSA and is required to fix BCM5301x support.
