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 BCM2711 on the Compute Module provides the built-in
xHCI.

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
