arm64: dts: mediatek: cherry: Enable T-PHYs and USB XHCI controllers

Add USB functionality by enabling the required PHYs and the XHCI
controllers.
This enables all of the supported USB ports on the Cherry boards.

Please note that u3phy1 also enables u3port1, which is configured
to be a PCI-Express PHY for the second PCIe controller that is
found on the MT8195 SoC, which will be enabled in a later commit.
