net: dsa: microchip: monitor potential faults in half-duplex mode
The errata DS80000754 recommends monitoring potential faults in
half-duplex mode for the KSZ9477 family.
half-duplex is not very common so I just added a critical message
when the fault conditions are detected. The switch can be expected
to be unable to communicate anymore in these states and a software
reset of the switch would be required which I did not implement.
Fixes: b987e98e50ab ("dsa: add DSA switch driver for Microchip KSZ9477")
