[U-Boot] [PATCH V2] mpc83xx:pcie:bugfix for mpc83xx pcie enumeration

[Baidu Boy]

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().
