This patchset adds trace event support for FW-First Protocol Errors.

Reworked the patchset to reuse the work item written by Ira for handling
CPER events.

I understand this patchset also schedules the cxl_pci driver to look at
potentially "non-device" errors as Terry's port error handling patches are
under review. However, I'm also fine to just confine it until FMLD as of
now. Looking for feedbacks here.
