6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Manivannan Sadhasivam <redacted>

[ Upstream commit a3b3a060b696d964c769a7d9dc5835c79e4fe964 ]

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 PHY on this board, feeding 1.2V to vdda-phy and 0.9V to
vdda-pll.

Fix it by swapping the two supplies back.
