Revert f4c55c5a3f ("PCI: designware: Program ATU with untranslated
address").

Note that dra7xx_pcie_host_init() now modifies pp->io_base, but we still
need the original value for dw_pcie_setup() in the path below, so this adds
a new io_base_tmp member.  It will be removed later when dw_pcie_setup() is
removed.

  dra7xx_add_pcie_port
    dw_pcie_host_init
      pp->io_base = range.cpu_addr
      pp->io_base_tmp = range.cpu_addr            # <-- added
      pp->ops->host_init
      dra7xx_pcie_host_init                       # ops->host_init
	pp->io_base &= DRA7XX_CPU_TO_BUS_ADDR     # <-- modified
      pci_common_init_dev(..., &dw_pci)
	pcibios_init_hw
	  hw->setup
	  dw_pcie_setup                           # hw_pci.setup
	    pci_ioremap_io(..., pp->io_base_tmp)  # <-- original addr required
