arm64: dts: qcom: glymur: Fix swapped USB QMP PHY vdda-phy/vdda-pll supplies

Browse Source 
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
DisplayPort QMP PHY on this SoC. But these two supplies are swapped for
the USB QMP PHYs on this board, feeding 1.2V to vdda-phy and 0.72V/0.83V
to vdda-pll.

Fix it by swapping the two supplies back.
