As a result, fatal errors are not logged or handled as needed for CXL PCIe upstream switch port devices. Update the aer_get_device_err_info() function to read the UCE fatal status for all CXL PCIe port devices. The fatal error status will be used in future patches implementing CXL PCIe port error handling and logging.
