Eliminate the following clang compilation warnings by including
necessary header files:

  arch/x86/lib/misc.c:7:5: warning: no previous prototype for function 'num_digits' [-Wmissing-prototypes]
  int num_digits(int val)
      ^
  arch/x86/lib/misc.c:7:1: note: declare 'static' if the function is not intended to be used outside of this translation unit
  int num_digits(int val)
  ^
  static
