mpc85xx: remove local bus initialisation 

The early initialisation of chip select 0 (boot flash) is removed
from cpu initialisation. This removes the dependency on board
base address definition.

Consequently, cpu_init_f is not called in the start-up code but
added to the init call list as cpu_init_r. Also the file
arch/ppc/mach-mpc85xx/fsl_lbc.c is deleted.
