This factors out the common bits of arch/powerpc/xmon/start_*.c into
a new nonstdio.c, and removes some stuff that was supposed to make
xmon's I/O routines somewhat stdio-like but was never used.
It also makes the parsing of the xmon= command line option common,
so that ppc32 can now use xmon={off,on,early} also.
