Subject: [PATCH v2] cxl/core: Fix the UUID of CXL vendor debug Log identifier

Fix the definition value of DEFINE_CXL_VENDOR_DEBUG_UUID to match the
CXL r3.1 specification, although this value is not currently used.

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 r2.0 Table 169
CXL spec r3.0 Table 8-62
CXL spec r3.1 Table 8-71

Fixes: 49be6dd80751 ("cxl/mbox: Move command definitions to common location")
