Hi,

Since we have that sysdev pointer, we need to use it also when
assigning the ACPI companion for the root hub. That should remove the
need to "manually" assign the ACPI companion to the controller device
in the xhci glue drivers like dwc3-host.c.

Assigning the ACPI companion in those glue drivers is very
problematic, because it screws up the fwnode->secondary pointer. But
as said, since we have that sysdev pointer, there is no need to
manually set it. sysdev pointer should always point to the correct
physical device from firmware PoW.

thanks,
