* Freescale 83xx and 512x PCI bridges

Freescale 83xx and 512x SOCs include the same PCI bridge core.

83xx/512x specific notes:
- reg: should contain two address length tuples
    The first is for the internal PCI bridge registers
    The second is for the PCI config space access registers

Example (MPC8313ERDB)

		cell-index = <1>;
		interrupt-map-mask = <0xf800 0x0 0x0 0x7>;
