[PATCH 3/6] dt-bindings: interrupt-controller: amazon,al-fic: add error/fatal groups

[Eliav Farber]

FIC v2 and later expose two additional interrupt groups alongside the
legacy group - an error group and a fatal group - each described by its
own node and matched by a distinct compatible string. Turn the single
compatible into an enum covering all three:

  amazon,al-fic         - legacy group
  amazon,al-fic-error   - error group
  amazon,al-fic-fatal   - fatal group
