Subject: [RFC PATCH 00/10] net: dsa: b53: fix BCM5325 support

These patches get the BCM5325 switch working with b53.

There are still some sporadic errors related to FDB, but at least the
switch is working now:
bcm53xx fffe4800.ethernet-mii:1e: port 0 failed to add d6:67:0c:XX:XX:XX vid 1 to fdb: -28
bcm53xx fffe4800.ethernet-mii:1e: port 0 failed to add 5c:4c:a9:XX:XX:XX vid 0 to fdb: -28
bcm53xx fffe4800.ethernet-mii:1e: port 0 failed to add 5c:4c:a9:XX:XX:XX vid 1 to fdb: -28
bcm53xx fffe4800.ethernet-mii:1e: port 0 failed to delete d6:67:0c:XX:XX:XX vid 1 from fdb: -2

I'm not really sure that everything here is correct since I don't work for
Broadcom and all this is based on the public datasheet available for the
BCM5325 and my own experiments with a Huawei HG556a (BCM6358).
