x86: cpufeature: move processor tracing out of scattered features
Processor tracing is already enumerated in word 9 (CPUID[7,0].EBX),
so do not duplicate it in the scattered features word.

without talking to x86 maintainers and Borislav?
This wants to go through TIP or at least reviewed and acked.
Thanks,
