net: bcmgenet: use MAC link status for fixed phy

[ Upstream commit c3c397c1f16c51601a3fac4fe0c63ad8aa85a904 ]

When using the fixed PHY with GENET (e.g. MOCA) the PHY link
status can be determined from the internal link status captured
by the MAC. This allows the PHY state machine to use the correct
link state with the fixed PHY even if MAC link event interrupts
are missed when the net device is opened.
