powerpc/xmon: Add __printf annotation to xmon_printf()
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.
