docs: net: dsa: document port_fast_age
The provided information about FDB flushing is not really up to date.
The DSA core automatically calls port_fast_age() when necessary, and
drivers should just implement that rather than hooking it to
port_bridge_leave, port_stp_state_set and others.
Fixes: 732f794c1baf ("net: dsa: add port fast ageing")
