[PATCH] arm64: dts: imx8mm-venice: Fix PCI bus nodes

[Rob Herring]

The imx8mm-venice boards PCI bus nodes are a complete mess. The
unit-addresses are wrong. The PCI bridge nodes are incomplete missing
"device_type" and "ranges" and just wrong for "#address-cells" and
"#size-cells" values.

All of these issues are reported warnings if anyone bothered to pay
attention. Sigh.

The kernel may have happened to work because it only looks at "reg"
to assign the DT nodes to PCI devices. Based on that, I'm assuming "reg"
is correctly matching the devices present, and the unit-addresses are
wrong. Presumably the bootloader fills in "local-mac-address" with
something valid. Hopefully it too uses "reg" rather than the path.

Fixes: afb424b99e0f ("arm64: dts: imx8mm-venice*: add PCIe support")
