The intreq_pcim_lperr interrupt carries Root Port AER notifications,
separately from the integrated MSI receiver interrupt. Describe it with
the "aer" name so the controller driver can use it for Root Port error
reporting.

Keep the fifth interrupt optional so existing device trees remain
valid. Extend the example accordingly.
