Subject: [PATCH] ARM: dts: bcm2711-rpi-4-b: Fix pcie0's unit address
Date:   Mon, 30 Aug 2021 12:39:09 +0200

dtbs_check currently complains that:

arch/arm/boot/dts/bcm2711-rpi-4-b.dts:220.10-231.4: Warning
(pci_device_reg): /scb/pcie@7d500000/pci@1,0: PCI unit address format
error, expected "0,0"

Unsurprisingly pci@0,0 is the right address, as illustrated by its reg
property:

	&pcie0 {
		pci@0,0 {
			/*
			 * As defined in the IEEE Std 1275-1994 document,
			 * reg is a five-cell address encoded as (phys.hi
			 * phys.mid phys.lo size.hi size.lo). phys.hi
			 * should contain the device's BDF as 0b00000000
			 * bbbbbbbb dddddfff 00000000. The other cells
			 * should be zero.
			 */
			reg = <0 0 0 0 0>;
		};
	};

The bus is clearly 0. So fix it.
