When PCIe AER is in FW-First, OS should process CXL Protocol errors from
CPER records. Introduce support for handling and logging CXL Protocol
errors.
The defined trace events cxl_aer_uncorrectable_error and
cxl_aer_correctable_error trace native CXL AER endpoint errors. Reuse them
to trace FW-First Protocol errors.
Since the CXL code is required to be called from process context and
GHES is in interrupt context, use workqueues for processing.
Similar to CXL CPER event handling, use kfifo to handle errors as it
simplifies queue processing by providing lock free fifo operations.
Add the ability for the CXL sub-system to register a workqueue to
process CXL CPER protocol errors.
