simplify 'struct ucode_cpu_info' and related operational logic.
reduce a number of similar 'microcode version' messages by printing a
single message for all cpus with equal microcode version, like:
Would be useful on systems with many cores.
On AMD multi-socket systems often you have the same CPU revisions and
thus you'd like to have similar ucode on all cores. Hence there is a
high chance that your code would reduce the amount of microcode log
messages during boot.
I'd like to test it but would need patches that do apply ...
