arm64: dts: qcom: ipq9574: Fix USB vdd info 



USB phys in ipq9574 use the 'L5' regulator. The commit ec4f0476
("arm64: dts: qcom: ipq9574: Enable USB") incorrectly specified it as
'L2'. Because of this when the phy module turns off/on its regulators,
the wrong regulator is turned off/on resulting in 2 issues, namely the
correct regulator related to the USB phy is not turned off/on and the
module powered by the incorrect regulator is affected.

Fixes: ec4f0476 ("arm64: dts: qcom: ipq9574: Enable USB")
