The CXL AER service will be updated to support CXL PCIe port error

recovery handling.
Recovery handling by panic? :) That's an interesting form of recovery..
Yes, Dan requested all UCE (fatal and non-fatal) are handled by panic in order
to limit the blast radius of corruption in the case of UCE.
That's fair enough. Maybe it should be called attempted recovery handling ;)
This is fine.

I'll add "attempted" recovery to the commit message.

The recovery logic in cxl_do_recovery() (not using the panic) is also tested as well.

Add PCI_ERS_RESULT_PANIC enumeration to pci_ers_result type.
