This adds testing for the powernv machine, and adds a gitlab-ci test
group instead of specifying all tests in .gitlab-ci.yml.

This moves merges ppc64 directories and files into powerpc, and
merges the 3 makefiles into one.
The configure --arch=powerpc option is aliased to ppc64 for
good measure.

Not all powerpc CPUs provide MMU support. Define vm_available() that is
true by default but archs can override it. Use this to run VM tests.

Add support for radix MMU, 4kB and 64kB pages.
This also adds MMU interrupt test cases, and runs the interrupts
test entirely with MMU enabled if it is available (aside from
machine check tests).

powerpc SMP support is very primitive and does not set up a first-class
runtime environment for secondary CPUs.
This reworks SMP support, and provides a complete C and harness
environment for the secondaries, including interrupt handling, as well
as IPI support.
