mpc83xx: fix pcie enumeration

Browse Source 
This patch fix a problem for the pcie enumeration for mpc83xx cpus.  Without
this we will not  get correct value in hose->regions[...].

The pointer *reg in function mpc83xx_pcie_init_bus() shall not be changed.
Because we will use this pointer as a parameter to call function
mpc83xx_pcie_register_hose().
