[PATCH v2 2/2] ARM: dts: bcm2711-rpi-4-b: Fix usb's unit address

[Nicolas Saenz Julienne]

The unit address is supposed to represent '<device>,<function>'. Which
are both 0 for RPi4b's XHCI controller. On top of that although
OpenFirmware states bus number goes in the high part of the last reg
parameter, FDT doesn't seem to care for it[1], so remove it.
