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

commit 09d385679487c58f0859c1ad4f404ba3df2f8830 upstream.

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.
