Subject: x86/lib/cpu: Address missing prototypes warning
Git-commit: 04f5bda84b0712d6f172556a7e8dca9ded5e73b9
Patch-mainline: 5.3-rc4
References: git-fixes

When building with W=1, warnings about missing prototypes are emitted:

  CC      arch/x86/lib/cpu.o
arch/x86/lib/cpu.c:5:14: warning: no previous prototype for 'x86_family' [-Wmissing-prototypes]
    5 | unsigned int x86_family(unsigned int sig)
      |              ^~~~~~~~~~
arch/x86/lib/cpu.c:18:14: warning: no previous prototype for 'x86_model' [-Wmissing-prototypes]
   18 | unsigned int x86_model(unsigned int sig)
      |              ^~~~~~~~~
arch/x86/lib/cpu.c:33:14: warning: no previous prototype for 'x86_stepping' [-Wmissing-prototypes]
   33 | unsigned int x86_stepping(unsigned int sig)
      |              ^~~~~~~~~~~~

Add the proper include file so the prototypes are there.
