This patchset is for PCI hotplug.


pcibios_setup_bus_devices which sets DMA and IRQs of PCI device is called
only when boot. DMA setting in probe for PCI driver, like dma_set_mask,
does not work on powerpc platform. So it is need to set DMA and IRQs of
PCI device when hotplug.

1. Moving pcibios_setup_bus_devices code to pcibios_device_change_notifier
   which is registered to bus notifier in pcibios_init.
2. Removing caller and callee of pcibios_setup_bus_devices bus notifier
   works instead of pcibios_setup_bus_devices.
3. Using this bus notifier for microblaze because microblaze/PCI is similer
   with powerpc/PCI.

[PATCH v2 1/2] powerpc/PCI: Add pcibios_device_change_notifier for powerpc
[PATCH v2 2/2] microblaze/PCI: Add pcibios_device_change_notifier for microblaze
