[PATCH 3/3] net: dwc_eth_qos: set proper DT node for phy device

[Rasmus Villemoes]

Similar to what was done for the FEC driver in commit
89b5bd54c1a4 (net: fec: Allow the PHY node to be retrieved), make sure
the PHY is associated with the right device tree node, so that phy
specific DT properties is accessible by the phy driver.

This is required on a custom iMX8MP board with a ti,dp83867 phy
sitting in front of the eqos interface.
