Bowman, Terry Oct. 25, 2024, 9:02 p.m. UTC 
The AER service driver's aer_get_device_error_info() function doesn't read
uncorrectable (UCE) fatal error status from PCIe upstream port devices,
including CXL upstream switch ports. As a result, fatal errors are not
logged or handled as needed for CXL PCIe upstream switch port devices.

Update the aer_get_device_error_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 uncorrectable error handling and logging.
