[PATCH v12 02/23] x86: move cpuid_count_leaf from cpuid.c to processor.h.

[Yi Sun <yi.y.sun@linux.intel.com>]

This patch moves 'cpuid_count_leaf' from cpuid.c to processor.h to
make it available to external codes.

v9:
    - create this patch alone to move 'cpuid_count_leaf'.
      (suggested by Wei Liu)
v6:
    - use 'struct cpuid_leaf' in psr.c. So we have to access 'cpuid_count_leaf'
      which has to be moved to processor.h.
      (suggested by Andrew Cooper)
