Looks like mvswitch driver tries to check chip here and got an
expected value 0x060X from register 3. So on the one hand the driver
is functioning, but on the other hand it can not detect switch IC.
Can you go to the /sys/class/mdio_bus/ and for each bus check driver
and ID of the each detected device. E.g.:
# cd /sys/class/mdio_bus
# ls -l */*/driver
# ls -l */*/phy_id
# cat */*/phy_id
