[PATCH RESEND 2/2] arm64: dts: mediatek: mt8195: add ssusb support

[Fabien Parent]

Add SSUSB support for MT8195. In order to not break any boards, this
commit also enable SSUSB for every board that has xhci0 enabled. The
boards are configured as host-only, in order to not change the current
behavior of the interface.
