arm64: dts: mediatek: mt8195-cherry: Mark USB 3.0 on xhci1 as disabled

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.
