Merge branch 'pci/host-probe-refactor'

- Use pci_host_bridge.windows list directly instead of splicing in a
  temporary list for cadence, mvebu, host-common (Rob Herring)

- Use pci_host_probe() instead of open-coding all the pieces for altera,
  brcmstb, iproc, mobiveil, rcar, rockchip, tegra, v3, versatile, xgene,
  xilinx, xilinx-nwl (Rob Herring)

- Convert to devm_platform_ioremap_resource_byname() instead of open-coding
  platform_get_resource_byname() and devm_ioremap_resource() for altera,
  cadence, mediatek, rockchip, tegra, xgene (Dejin Zheng)

- Convert to devm_platform_ioremap_resource() instead of open-coding
  platform_get_resource() and devm_ioremap_resource() for aardvark,
  brcmstb, exynos, ftpci100, versatile (Dejin Zheng)

- Remove redundant error messages from devm_pci_remap_cfg_resource()
  callers (Dejin Zheng)

- Drop useless PCI_ENABLE_PROC_DOMAINS from versatile driver (Rob Herring)

- Default host bridge parent device to the platform device (Rob Herring)

- Drop unnecessary zeroing of host bridge fields (Rob Herring)

- Use pci_is_root_bus() instead of tracking root bus number separately in
  aardvark, designware (imx6, keystone, designware-host), mobiveil,
  xilinx-nwl, xilinx, rockchip, rcar (Rob Herring)

- Set host bridge bus number in pci_scan_root_bus_bridge() instead of each
  driver for aardvark, designware-host, host-common, mediatek, rcar, tegra,
  v3-semi (Rob Herring)

- Use bridge resources instead of parsing DT 'ranges' again for cadence
  (Rob Herring)

- Remove private bus number and range from cadence (Rob Herring)

- Use devm_pci_alloc_host_bridge() to simplify rcar (Rob Herring)

- Use struct pci_host_bridge.windows list directly rather than a temporary
  (Rob Herring)

- Reduce OF "missing non-prefetchable window" from error to warning message
  (Rob Herring)

- Convert rcar-gen2 from old Arm-specific pci_common_init_dev() to new
  arch-independent interfaces (Rob Herring)

- Move DT resource setup into devm_pci_alloc_host_bridge() (Rob Herring)

- Set bridge map_irq and swizzle_irq to default functions; drivers that
  don't support legacy IRQs (iproc) need to undo this (Rob Herring)
