cxl/events: Add Component Identifier formatting for CXL spec rev 3.1
Add Component Identifier formatting for CXL spec rev 3.1, Section 8.2.9.2.1, Table 8-44. Examples for Component Identifier format in trace log, validity_flags='CHANNEL|RANK|DEVICE|COMPONENT|COMPONENT PLDM FORMAT' \ comp_id=03 74 c5 08 9a 1a 0b fc d2 7e 2f 31 9b 3c 81 4d \ comp_id_pldm_valid_flags='PLDM Entity ID | Resource ID' \ pldm_entity_id=74 c5 08 9a 1a 0b pldm_resource_id=fc d2 7e 2f \ validity_flags='COMPONENT|COMPONENT PLDM FORMAT' \ comp_id=02 74 c5 08 9a 1a 0b fc d2 7e 2f 31 9b 3c 81 4d \ comp_id_pldm_valid_flags='Resource ID' \ pldm_entity_id=0x00 pldm_resource_id=fc d2 7e 2f If the validity flags for component ID/component ID format or PLDM ID or resource ID are not set, then pldm_entity_id=0x00 or pldm_resource_id=0x00 would be printed. Component identifier formatting is used in the subsequent patches.
