ARM: dts: bcm2711: Fix xHCI power-domain
During s2idle tests on the Raspberry CM4 the VPU firmware always crashes
on xHCI power-domain resume:
root@raspberrypi:/sys/power# echo freeze > state
[ 70.724347] xhci_suspend finished
[ 70.727730] xhci_plat_suspend finished
[ 70.755624] bcm2835-power bcm2835-power: Power grafx off
[ 70.761127] USB: Set power to 0
[ 74.653040] USB: Failed to set power to 1 (-110)
This seems to be caused because of the mixed usage of
raspberrypi-power and bcm2835-power at the same time. So avoid
the usage of the VPU firmware power-domain driver, which
prevents the VPU crash.
