 An abstraction around TCE kill. This allows host OS kernels to use an OPAL
 call if they don't know the model specific invalidation method.

   if PHB model doesn't support this call. This is likely
   true for systems before POWER9/PHB4.
   Do *NOT* rely on this call existing for systems prior to
   POWER9 (i.e. PHB4).
