Subject: [PATCH 2/7] arm64: dts: mediatek: mt8195: add ssusb support

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.
