Benjamin Herrenschmidt 8b8da35804 powerpc/pci: Split pcibios_fixup_bus() into bus setup and device setup
Currently, our PCI code uses the pcibios_fixup_bus() callback, which
is called by the generic code when probing PCI buses, for two
different things.

One is to set up things related to the bus itself, such as reading
bridge resources for P2P bridges, fixing them up, or setting up the
iommu's associated with bridges on some platforms.

The other is some setup for each individual device under that bridge,
mostly setting up DMA mappings and interrupts.

The problem is that this approach doesn't work well with PCI hotplug
when an existing bus is re-probed for new children.  We fix this
problem by splitting pcibios_fixup_bus into two routines:

	pcibios_setup_bus_self() is now called to setup the bus itself

	pcibios_setup_bus_devices() is now called to setup devices

pcibios_fixup_bus() is then modified to call these two after reading the
bridge bases, and the OF based PCI probe is modified to avoid calling
into the first one when rescanning an existing bridge.

[paulus@samba.org - fixed eeh.h for 32-bit compile now that pci-common.c
is including it unconditionally.]
