Subject: usb: dwc3: Add ACPI support for xHCI ports

Git-commit: 11c39809070fc0eb3aacb0d9ee71cd3678144f66
Patch-mainline: v5.7-rc1
References: jsc#SLE-12251

The ACPI companion of the adapter has to be set for xHCI controller
code to read and attach the ports described in the ACPI table.
Use ACPI_COMPANION_SET macro to set this.
