[PATCH 04/28] arm64: dts: qcom: sdm845: Fix swapped USB QMP PHY vdda-phy/vdda-pll supplies

From: Manivannan Sadhasivam <[email protected]>

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 these boards, feeding 1.2V to vdda-phy and 0.88V to
vdda-pll.

Fix it by swapping the two supplies back.
