[RFC V2 04/10] hw/cxl: Add Streamlined Virtual Channel (SVC) property to CXL ports

[Shrihari E S <shrihari.s@samsung.com>]

Add Unordered IO (UIO) dependent property SVC to CXL ports.

The following properties are added to CXL ports:
    - x-svc: To enable SVC capability in the port

Note: 256B flit mode property was already added in CXL ports, so reused it.
