tests: Temporarily disable ppc64 cpu tests

The upcoming commits will make heavy modifications to the ppc64
driver, split so that it's easier to review the changes.

Instead of updating the test cases so that they pass, possibly
only to update them again with the following commit, disable them
for the time being.

Another commit will update them all in one go once all required
changes are in place.
