[POWERPC] Make the debugfs "powerpc" dir globally accessible
The prom.c debugging code creates a "powerpc" directory in debugfs, which is nice, but doesn't allow any other debugging code to stick things under "powerpc" in debugfs. So make it global. While we're there we should make the prom.c debugging code depend on CONFIG_DEBUG_FS, because it doesn't work otherwise.
