nb/intel/i440bx/debug.c: Refactor newlines and save some printk calls

There are two conditions within the config space dump code, one to
print offset, one at the end to put a newline. Tweak the printk
strings so the first conditioned printk does it all and moves the
second printk out of the loop to the very end.
