sysutils/devcpu-data: Update AMD microcode, add cpu 17h microcode,
drop malfunctioning individual "AMD-XXX" files.

On the few machines that actually have microcode updates, chopping up the
microcode is incorrect and results in a failure to update. Don't do that.

I personally run this on my FX-8150 and this has been tested by a few others.
