Subject: [PATCH RESEND] x86/cpu/intel: replace deprecated strcpy with strscpy

strcpy is deprecated due to lack of bounds checking.
This patch replaces strcpy with strscpy, the recommended alternative for
null terminated strings, to follow best practices.

This patch was reviewed by H. Peter Anvin and (by my understanding)
was deemed ok to apply. I have not added a Reviewed-by tag as H.
Peter Anvin did not do so.

The last time I resent this patch was during the merge window so it
understandably did not get applied or further reviewed.
I have resent it again as the merge window has now closed, hopefully
so it can be further reviewed and applied
