[PATCH 5/7] Documentation: x86: Update smp_num_siblings/x86_max_cores description

[Zhang Rui <rui.zhang@intel.com>]

smp_num_siblings/cpuinfo_x86.x86_max_cores are retrieved via CPUID EAX
bit_shift value, and they represent the maximum possible number of threads
in a core, and the maximum possible number of cores in a package.

Update the smp_num_siblings/cpuinfo_x86.x86_max_cores description in the
documentation.
