Traditionally these were all serialized by the rtnl_lock(), but now it is possible that DSA calls ->port_fdb_add and ->port_fdb_del without holding that lock. So the driver must have its own serialization logic. Add a mutex and hold it from all entry points (->port_fdb_{add,del,dump}, ->port_mdb_{add,del}).

Years ago when b53 was an OpenWrt downstream driver (with configuration based on sometimes bugged NVRAM) there was a need for a fixup. In case of forcing fixed link for (incorrectly specified) port 5 the code had to actually setup port 8 link. For upstream b53 driver with setup based on DT there is no need for that workaround. In DT we have and require correct ports setup.

IMP port may be different than CPU port - especially on devices with multiple CPU ports. For that reason it's required to explicitly note IMP port index and check for it when choosing a register to use. This commit fixes BCM5301x support. Those switches use CPU port 5 while their IMP port is 8. Before this patch b53 was trying to program port 5 with B53_PORT_OVERRIDE_CTRL instead of B53_GMII_PORT_OVERRIDE_CTRL(5). It may be possible to also replace "cpu_port" usages with dsa_is_cpu_port() but that is out of the scope of thix BCM5301x fix.

That made b53 modify unrelated registers and is one of reasons for a broken BCM5301x support. This problem exists for years but DSA_MAX_PORTS usage has changed few times.
