dt-bindings: phy: qcom,sa8775p-dwmac-sgmii-phy: add named voltage rails and deprecate phy-supply
The Qualcomm SGMII SerDes PHY has two distinct voltage supply rails,
vdda-0p9 and vdda-1p2. The binding incorrectly described only a single
generic supply via 'phy-supply'.
Deprecate 'phy-supply' and instead add two named supply properties. The
0.9V rail draws a peak current of 46 mA and the 1.2V rail draws 15 mA.
