The SerDes PHY nodes were configured with 'phy-supply = <&vreg_l5a>',
which was incorrect on two counts: vreg_l5a is not a supply the PHY
requires, and only one rail was described whereas the hardware needs
two.
The PHY requires vdda-0p9 (vreg_l4a) and vdda-1p2 (vreg_l1c). Replace
the incorrect phy-supply with these two named properties on both the
base EVK node and the IFP mezzanine overlay.
