[U-Boot] [PATCH] net: xilinx_axiemac: Fill the phy node pointer in phydev

[Michal Simek]

From: Siva Durga Prasad Paladugu <siva.durga.paladugu at xilinx.com>

This patch assings the phynode pointer to the phydev node as it is needed
later in the corresponding phy driver to read phy properties from DT.
