In contrast to the Raspberry Pi 4, the Compute Module 4 or the IO board
does not have a VL805 USB 3.0 host controller, which is connected via
PCIe. Instead, the Compute Module provides the built-in
xHCI of the BCM2711 SoC.
Changes in V4:
- use "brcm,xhci-brcm-v2" as fallback compatible as suggested by
Conor & Florian
Changes in V3:
- introduce a new compatible for BCM2711 in order to make the
power domain dependency SoC specific, which also results in
a driver change
Changes in V2:
- adjust xHCI compatible as suggested by Justin & Florian
- keep xHCI disabled in order to let the bootloader decide which
USB block should be enabled, which result in a drop of patch 3
