tests: Boot PowerPC using PMU instead of CUDA for power management

Browse Source 
A recent refactoring of CUDA command code has exposed a bug in OpenBIOS [1]
which was causing system powerdown and system reset to fail, thus causing
the QEMU instance to hang. This in turn caused the grub-shell command to
timeout causing it to return an error code when the test actually completed
successfully.

Since it could be a while before the patch fixing this issue in OpenBIOS
filters down to the average distro, switch to PMU to allow powerdowns and
reboots to work as expected.
