Make the ppc32 pcibios_alloc_controller take a device node to match
the ppc64 prototypes and have it set arch_data.

Removed the remants of bus_offset and use self_busno in the mv64x60 case
and use pci_assign_all_buses on 83xx/85xx.

83xx/85xx have multiple PHBs and the firmwares on these devices tend not
to handle topologies with P2P bridges well so we let Linux just reassign
the bus numbers to match.

The Freescale and Marvell PCI controllers dont require explicit setting for
type 1 config cycles.  They handle producing them by implicitly looking at the
bus, devfn.

The TSI108 and 52xx don't use the generic PCI indirect code and thus don't
bother with set_cfg_type.

This patch adds PCI bridge support for the Marvell mv64x60 chip.
We also provide the ability to read/write the mv64x60 hotswap
register via sysfs if the hs_reg_valid property is set in the
device tree.
