powerpc/xmon: Add __printf annotation to xmon_printf()

Browse Source 
This allows the compiler to verify the format strings vs the types of
the arguments.

Update the other prototype declarations in asm/xmon.h.

Silence warnings (triggered at W=1) by adding relevant __printf
attribute. Move #define at bottom of the file to prevent conflict with
gcc attribute.

Solves the original warning:

  arch/powerpc/xmon/nonstdio.c:178:2: error: function might be
  possible candidate for ‘gnu_printf’ format attribute

In turn this uncovered many formatting errors in xmon.c, all fixed in
this patch.
