Log message:
Add support for POWER8 (and maybe earlier) CPUs. Not sure if this works on
real hardware, but it gets the kernel booting on QEMU emulating a POWER8
CPU so it's a step in the right direction.
This establishes a way to distinguish CPU features based on the AT_HWCAP
and AT_HWCAP2 features documented in the ELF ABI. Also use this to
determine the availability of the DARN instruction instead of keying of
the processor model.
