All CXL devices that support a debug log shall support the Vendor Debug Log to allow the log to be accessed through a common host driver, for any device, all versions of the CXL specification define the same value with Log Identifier of: 5e1819d9-11a9-400c-811f-d60719403d86 Refer to CXL spec r3.1 Table 8-71 Fix the definition value of DEFINE_CXL_VENDOR_DEBUG_UUID to match the CXL specification.
