powerpc/mpc85xx: Fix DDR TLB mapping leftover
Commit f29f804a93e87c17670607641d120f431a3b0633 generalized the TLB mapping function, but made the DDR mapping leftover size to zero, causing the message not printed. Signed-off-by: York Sun <yorksun@freescale.com> CC: Alexander Graf <agraf@suse.de> CC: Scott Wood <scottwood@freescale.com>
