[PATCH 03/13] net: stmmac: dwmac-rk: Allow the driver to probe when phy-supply is not present

The phy-supply is an optional regulator, so we should not treat
as an error when phy-supply is not passed in the device tree.

This allows the dwmac-rk driver to probe when phy-supply is not
present in the dts.
