[PATCH 27/28] arm64: dts: qcom: sa8155p-adp: Fix swapped USB and UFS QMP PHY vdda-phy/vdda-pll supplies

From: 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 and UFS 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.

Fixes: 5b85e8f2225c ("arm64: dts: qcom: sa8155p-adp: Add base dts file")
