atl1c: fix Mikrotik 10/25G NIC detection
Since Mikrotik 10/25G NIC MDIO op emulation is not 100% reliable,
on rare occasions it can happen that some physical functions of
the NIC do not get initialized due to timeouted early MDIO op.
This changes the atl1c probe on Mikrotik 10/25G NIC not to
depend on MDIO op emulation.
