Another fix for xmon on non-standard MMU machines

[David Gibson <david@gibson.dropbear.id.au>]

This patch stops xmon from attempting to print the segment registers
on machines where CONFIG_PPC_STD_MMU is not set.  This prevents xmon
from causing an exception when the 'S' command is used on the 4xx (and
others).
