Cédric Le Goater c035851ac0 ppc/pnv: fix XSCOM core addressing on POWER9
The XSCOM base address of the core chiplet was wrongly calculated. Use
the OPAL macros to fix that and do a couple of renames.

Cédric Le Goater 09279d7e7b ppc/pnv: change core mask for POWER9
When addressed by XSCOM, the first core has the 0x20 chiplet ID but
the CPU PIR can start at 0x0.

Eric Blake 78b27bade1 libqtest: Add qtest_[v]startf()
We have several callers that were formatting the argument strings
themselves; consolidate this effort by adding new convenience
functions directly in libqtest, and update some call-sites that
can benefit from it.

Note that the new functions qtest_startf() and qtest_vstartf()
behave more like qtest_init() (the caller must assign global_qtest
after the fact, rather than getting it implicitly set).  This helps
us prepare for future patches that get rid of the global variable,
by explicitly highlighting which tests still depend on it now.

David Gibson eaa477ca4e powernv: Don't test POWER9 CPU yet
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.

David Gibson ca8e4bf409 tests: add XSCOM tests for the PowerNV machine
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.
