[PATCH 26/28] arm64: dts: qcom: eliza-mtp: Fix swapped USB 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 the lower voltage (~0.8V)
and the vdda-pll supply to be the higher voltage (~1.2V), as used by the
UFS QMP PHY on this SoC. But these two supplies are swapped for the USB
QMP PHY on this board, feeding 1.15V to vdda-phy and 0.72V to vdda-pll.

Fix it by swapping the two supplies back.
