[PATCH -next] ARM: dts: integrator: fix PCI bus dtc warnings

[Lin Yujun]

An warning is reported when allmodconfig is used to compile the kernel of the ARM architecture:

arch/arm/boot/dts/arm/integratorap-im-pd1.dts:252.3-14: Warning (dma_ranges_format): /bus@c0000000/bus@c0000000/display@1000000:dma-ranges: empty "dma-ranges" property but its #address-cells (2) differs from /bus@c0000000/bus@c0000000 (1)
arch/arm/boot/dts/arm/integratorap.dts:161.22-206.4: Warning (pci_bridge): /pciv3@62000000: node name is not "pci" or "pcie"

arch/arm/boot/dts/arm/integratorap.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge'

Change the node name to pci to clear the build warning.

Fixes: 4952aa696a9f ("ARM: dts: integrator: Tag PCI host with device_type")

This does not fix the warning at all.

Maybe this one is fixed only... Drop all unrelated warnings, because
this is very confusing.

No, not a fix. It's just node naming.
