I applied this series to my pci/host-xilinx branch for v4.6.
Michal, you only explicitly acked the last patch, but that only makes
sense if I apply the whole series, so I applied your ack to all the
patches.
Someday somebody should rework pci_fixup_irqs() so that doesn't have
to be arch-dependent.
I reworked the changelogs as below.

PCI: xilinx: Don't call pci_fixup_irqs() on Microblaze
The Xilinx AXI PCIe Host Bridge Soft IP driver was previously only
supported on ARM (in particular, on ARCH_ZYNC), and pci_fixup_irqs() is
available there. But Microblaze will do IRQ fixup in pcibios_add_device(),
so pci_fixup_irqs() is not available on Microblaze.
Don't call pci_fixup_irqs() on Microblaze, so the driver can work on both
Zynq and Microblaze Architectures.

PCI: xilinx: Remove dependency on ARM-specific struct hw_pci
The Xilinx PCIe host controller driver uses pci_common_init_dev(), which
is ARM-specific and requires the ARM struct hw_pci. The part of
pci_common_init_dev() that is needed is limited and can be done here
without using hw_pci.
Create and scan the root bus directly without using the ARM
pci_common_init_dev() interface.
