powerpc: 83xx: pci: Remove need for get_immrbase from mpc83xx_add_bridge.
Modify mpc83xx_add_bridge to get config space register base address from
the device tree instead of immr + hardcoded offset.
83xx pci nodes have this change:
register properties now contain two address length tuples:
First is the pci bridge register base, this has always been there.
Second is the config base, this is new.
This is documented in dts-bindings/fsl/83xx-512x-pci.txt
The changes accomplish these things:
mpc83xx_add_bridge no longer needs to call get_immrbase
it uses hard coded addresses if the second register value is missing
