[PATCH] net: phy: micrel: Get phy node from phy-handle

[Jit Loon Lim]

From: Ley Foon Tan <ley.foon.tan at intel.com>

HSD #1509063521: Try to get phy node from "phy-handle" if can't find ethernet-phy subnode.
Lastly only use Ethernet node if can't find phy node from ethernet-phy
subnode and phy-handle.
