Both 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 where 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 nodes.
Fixes: 5ef26fb8b3ed ("arm64: dts: qcom: sa8775p-ride: enable the SerDes PHY")
