Serge Semin d1cf738f2b PCI: dwc: Add unroll iATU space support to dw_pcie_disable_atu() 
dw_pcie_disable_atu() was introduced by f8aed6ec62 ("PCI: dwc:
designware: Add EP mode support") and supported only the viewport version
of the iATU CSRs.

DW PCIe IP cores v4.80a and newer also support unrolled iATU/eDMA space.
Callers of dw_pcie_disable_atu(), including pci_epc_ops.clear_bar(),
pci_epc_ops.unmap_addr(), and dw_pcie_setup_rc(), don't work correctly when
it is enabled.

Add dw_pcie_disable_atu() support for controllers with unrolled iATU CSRs
enabled.
