I notcie the comment above this if statement is a bit stale since it
only mentions SKL and BXT, but not KBL, CFL, WHL, AML. Just to avoid
confusion, we might want to update that to indicate the mutual exclusion
applies to all gen9 except for GLK and that the mutual exclusion is no
longer relevant on gen10+.
