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.

Add a couple of tests on the XSCOM bus of the PowerNV machine for the
the POWER8 and POWER9 CPUs. The first tests reads the CFAM identifier
of the chip. The second test goes further in the XSCOM address space
and reaches the cores to read their DTS registers.
