Inappropriate comment (it's already *I*G*) and don't set MAS3_SX on I/O
regions.

Comment says *I*G but it's actually ****.

This says 128K, but elsewhere you map the LAW and TLB as 1M, and you
configure it as 64K in eLBC.

L2 SRAM, init ram, and CCSR do not belong under "Localbus".

Don't undef things that were never defined in the first place.  The only
place in the entire tree that CONFIG_SERIAL_SOFTWARE_FIFO exists at all
is a few similar undefs in other Freescale boards.

This is a pointless ifdef, and a pointless setting of PS2 since that's
already the default.

Please consider defaulting to -1 here, now that it no longer disables
bootdelay support at compile-time.
