[U-Boot] Olimex-A20-EVB ethernet stops working with latest U-boot, works with tag v2016.01

Hi Damiano,

Can you try revert the following patch and retest on your board?

    net: phy: do not read configuration register on reset
        
    When doing a software reset, the reset flag should be written without
    other bits set. Writing the current state will lead to restoring the
    state of the PHY (e.g. Powerdown), which is not what is expected from
    a software reset.

This patch breaks ethernet function of i.MX6 Quad Sabresd/Quad Sabreauto.
Not sure whether reverting this patch can help in your case or not. Please
try.

Thanks,
Peng.
