[PATCH 02/28] arm64: dts: qcom: sc8280xp-blackrock: Fix swapped USB QMP PHY vdda-phy/vdda-pll supplies

[Manivannan Sadhasivam via B4 Relay]

From: Manivannan Sadhasivam <manivannan.sadhasivam@xxxxxxxxxxxxxxxx>

The QMP PHY expects the vdda-phy supply to be around 0.88V and the
vdda-pll supply to be 1.2V. But these two supplies are swapped for the
USB QMP PHYs on this board, feeding 1.2V to vdda-phy and 0.9V to
vdda-pll.

Fix it by swapping the two supplies back.
