x86: Remove "x86 CPU features in debugfs" (CONFIG_X86_CPU_DEBUG)
CONFIG_X86_CPU_DEBUG, which provides some parsed versions of the x86
CPU configuration via debugfs, has caused boot failures on real
hardware. The value of this feature has been marginal at best, as all
this information is already available to userspace via generic
interfaces.
Causes crashes that have not been fixed + minimal utility -> remove.
See the referenced LKML thread for more information.
