You're using arch/ppc which is depreciated.  You should move to using
arch/powerpc (set ARCH=powerpc when compiling).  Devices are then
enabled in the device tree source file

Many things have changed with MPC5200 support in the last year, you
should also use the latest kernel release ( when it is
released.  If you use, then there is a trivial bug in the psc
serial port driver that you'll need to fix.  I'll include the link to
the patch below)
