[PATCH v1 2/2] arm64: dts: qcom: ipq9574: Fix USB vdd info

[Varadarajan Narayanan <quic_varada@xxxxxxxxxxx>]

USB phys in ipq9574 use the 'L5' regulator. The commit
ec4f047679d5 ("arm64: dts: qcom: ipq9574: Enable USB")
incorrectly specified it as 'L2'. Because of this when the phy
module turns off/on its regulators, 'L2' is turned off/on
resulting in 2 issues, namely 'L5' is not turned off/on and the
network module powered by the 'L2' is turned off/on.
