BV_RB and BV_CCU are supported on some devices (knp, but not glymur or
pakala, for ex).. we don't have a way to deal with that yet.

This doesn't yet _expose_ gen8 perfcntrs.  That small patch will come
after PERFCNTR_CONFIG ioctl is supported to ensure that everything gen8
and later supports the new kernel based counter collection/reservation
(so that backwards compat of old userspace on new kernel is limited to
a7xx and earlier).
