Subject: [PATCH 06/15] cxl/aer/pci: Introduce PCI_ERS_RESULT_PANIC to pci_ers_result type

The CXL AER service will be updated to support CXL PCIe port error
handling in the future. These devices will use a system panic during
recovery handling.

Add PCI_ERS_RESULT_PANIC enumeration to pci_ers_result type.
