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 Signed-off-by: John Rigby <jrigby@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

1* Freescale 83xx and 512x PCI bridges
2
3Freescale 83xx and 512x SOCs include the same pci bridge core.

583xx/512x specific notes:
6- reg: should contain two address length tuples
7 The first is for the internal pci bridge registers
8 The second is for the pci config space access registers
