[POWERPC] mpc5200: defconfigs for CM5200, Lite5200B, Motion-PRO and TQM5200

[POWERPC] mpc5200: defconfigs for CM5200, Lite5200B, Motion-PRO and TQM5200

Board-specific defconfigs based on current mpc5200_defconfig, archival
lite5200_defconfig, and [cm5200|motionpro|tqm5200]_defconfig from the
linux-2.6-denx tree. Kernels build using these defconfigs were verified
to boot with root filesystem mounted over NFS on Motion-PRO, TQM5200
and Lite5200B boards. CM5200 target was not tested due to hardware
unavailability.
