net: dsa: mv88e6xxx: Don't force link when using in-band-status
When a port is configured with 'managed = "in-band-status"' switch chips
like the 88E6390 need to propagate the SERDES link state to the MAC
because the link state is not correctly detected. This causes problems
on the 88E6185/88E6097 where the link partner won't see link state
changes because we're forcing the link.
To address this introduce a new device specific op port_sync_link() and
push the logic from mv88e6xxx_mac_link_up() into that. Provide an
implementation for the 88E6185 like devices which doesn't force the
link.
