[POWERPC] Add gcc format warnings to zImage printf()
This patch adds the correct attributes to the zImage's versions of printf to make gcc generate format string mismatch warnings. It also corrects several minor problems with format strings in the zImage thus discovered. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
