powerpc: add cpu_spec.cpu_features to vmcoreinfo

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

CPU features can be determined in makedumpfile, using
'cur_cpu_spec.cpu_features'.

This provides more data to makedumpfile about the crashed system, and
can help in filtering the vmcore accordingly.
