Subject: [PATCH v1 2/2] arm64: dts: qcom: ipq9574: Fix USB 'vdda-pll-supply'

From: Varadarajan Narayanan <quic_varada@...cinc.com>

The earlier patch ec4f047679d5, incorrectly used 'l2'
as the vdda-pll-supply. However, 'l5' is the correct
ldo that supplies power to the USB PHY.

Fixes: ec4f047679d5 ("arm64: dts: qcom: ipq9574: Enable USB")
Signed-off-by: Varadarajan Narayanan <quic_varada@...cinc.com>
