powerpc64/powernv: Use OPAL call for non-POWER8 PCI TCE reset

According to the OPAL documentation, only the POWER8 (PHB3) should use
the register write TCE reset method.  All others should use the OPAL
call.

On POWER9 the call is semantically identical to the register write, with
a wait for completion.
