Pali Rohár 72ea28d88d arm64: dts: marvell: armada-37xx: Remap IO space to bus address 0x0 
commit a1cc1697bb upstream.

Legacy and old PCI I/O based cards do not support 32-bit I/O addressing.

Since commit 64f160e19e ("PCI: aardvark: Configure PCIe resources from
'ranges' DT property") kernel can set different PCIe address on CPU and
different on the bus for the one A37xx address mapping without any firmware
support in case the bus address does not conflict with other A37xx mapping.

So remap I/O space to the bus address 0x0 to enable support for old legacy
I/O port based cards which have hardcoded I/O ports in low address space.

Note that DDR on A37xx is mapped to bus address 0x0. And mapping of I/O
space can be set to address 0x0 too because MEM space and I/O space are
separate and so do not conflict.

Remapping IO space on Turris Mox to different address is not possible to
due bootloader bug.
