[PATCH v1 3/4] x86: cpu: Add a few prototypes to the header file

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

The compiler is not happy to have no prototypes for the functions that
are not defined static. Add them. This helps avoiding the compiler warnings:

  arch/x86/cpu/cpu.c:197:13: warning: no previous prototype for ‘board_final_init’ [-Wmissing-prototypes]
  arch/x86/cpu/cpu.c:205:13: warning: no previous prototype for ‘board_final_cleanup’ [-Wmissing-prototypes]
  arch/x86/cpu/cpu.c:307:5: warning: no previous prototype for ‘reserve_arch’ [-Wmissing-prototypes]
