A couple of tests for the work-in-progress 'powernv' machine type attempt to test on POWER9 CPUs. However the POWER9 CPU support is incomplete and this doesn't really work. In particular the firmware image we have currently assumes the presence of the SDR1 register, which no longer exists on POWER9. We only got away with this so far, because of a different bug which added SDR1 to POWER9 even though it shouldn't be there. For now, remove POWER9 testing of powernv, POWER8 testing will do for now until the POWER9 support is more complete. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
