This patch breaks Ethernet on all my dwmac-sunxi, i.e. old GMAC, boards, with
the following error messages:

    sun7i-dwmac 1c50000.ethernet eth0: no phy at addr -1
    sun7i-dwmac 1c50000.ethernet eth0: stmmac_open: Cannot attach to
PHY (error: -19)

Reverting this patch fixes it.

It also breaks the A10/A10s, but that's probably because the sun4i-emac
driver doesn't recognize the "phy-handle" property.
