    Revert "net: bcmgenet: soft reset 40nm EPHYs before MAC init" · 6b6d017f

    This reverts commit 1f515486.
    
    This commit improved the chances of the umac resetting cleanly by
    ensuring that the PHY was restored to its normal operation prior
    to resetting the umac. However, there were still cases when the
    PHY might not be driving a Tx clock to the umac during this window
    (e.g. when the PHY detects no link).
    
    The previous commit now ensures that the unimac receives clocks
    from the MAC during its reset window so this commit is no longer
    needed. This commit also has an unintended negative impact on the
    MDIO performance of the UniMAC MDIO interface because it is used
    before the MDIO interrupts are reenabled, so it should be removed.
