[ Upstream commit 09d385679487c58f0859c1ad4f404ba3df2f8830 ] USB 3.0 on xhci1 is not used, as the controller shares the same PHY as pcie1. The latter is enabled to support the M.2 PCIe WLAN card on this design. Mark USB 3.0 as disabled on this controller using the "mediatek,u3p-dis-msk" property. Reported-by: Nícolas F. R. A.
