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().
