PCI/ERR: Recover from RCiEP AER errors
Add support for handling AER errors detected by Root Complex Integrated
Endpoints (RCiEPs). These errors are signaled to software natively via a
Root Complex Event Collector (RCEC) or non-natively via ACPI APEI if the
platform retains control of AER or uses a non-standard RCEC-like device.
When recovering from RCiEP errors, the Root Error Command and Status
registers are in the AER Capability of an associated RCEC (if any), not in
a Root Port. In the non-native case, the platform is responsible for those
registers and we can't touch them.
