[PATCH v5 3/3] arm64: dts: cix: Add USB3 PHY nodes for Sky1

[Hongliang Yang (杨宏亮)]

Add the USB3 PHY node for the CIX Sky1 SoC and enable both PHY ports
on the Radxa Orion O6 board.

Signed-off-by: Hongliang Yang <hongliang.yang at cixtech.com>
---
v4 -> v5:
- Fixed the #size-cells property order in the PHY node.
- Removed the unused phy.h include.
- Dropped the redundant status properties of the PHY port nodes and
  the corresponding board overrides.
