net: dsa: qca8k: add tracking state of master port
MDIO/MIB Ethernet require the master port and the tagger availabale to
correctly work. Use the new api master_state_change to track when master
is operational or not and set a bool in qca8k_priv.
We cache the first cached master available and we check if other cpu
port are operational when the cached one goes down.
This cached master will later be used by mdio read/write and mib request to
correctly use the working function.
qca8k implementation for MDIO/MIB Ethernet is bad. CPU port0 is the only
one that answers with the ack packet or sends MIB Ethernet packets. For
this reason the master_state_change ignore CPU port6 and only checks
CPU port0 if it's operational and enables this mode.
