[PATCH 3/3] arm64: dts: cix: add Sky1 USB/DP combo PHY

[Gary Yang]

Add the four USB/DP combo PHY nodes to the Sky1 SoC device tree and
enable them on the Radxa Orion O6.

Each PHY node describes its USB and DisplayPort lanes as child nodes,
points at the S5 system controller instance that controls lane muxing
and plug orientation, and is disabled by default so that boards that do
not route the port stay unaffected.
