mem/cxl-type3: Add sn option to provide serial number for PCI ecap
The Device Serial Number Extended Capability PCI r6.0 sec 7.9.3
provides a standard way to provide a device serial number as
an IEEE defined 64-bit extended unique identifier EUI-64.
CXL 2.0 section 8.1.12.2 Memory Device PCIe Capabilities and
Extended Capabilities requires this to be used to uniquely
identify CXL memory devices.
