[POWERPC] Include udbg.h when using udbg_printf

This fixes the error
	error: implicit declaration of function "udbg_printf"

We have a few spots where we reference udbg_printf() without #including
udbg.h.  These are within #ifdef DEBUG blocks, so unnoticed until we do
a #define DEBUG or #define DEBUG_LOW nearby.
