There can be error conditions within Intel BT firmware that can cause it
to get stuck, with the only way out being toggle the reset pin to the
device. (I do not have the details about the issues that lead to such
conditions, Intel folks copied here can elaborate if needed). Thus, this
is an effor to be able to toggle the reset line from the driver if it
detects such a situation. It makes few enhancements to the common
framework which I think may be useful for other unrelated problems.

usb: split code locating ACPI companion into port and device
usb: assign ACPI companions for embedded USB devices
(This basically allows ACPI nodes to be attached to the USB devices,
thus useful for any onboard / embedded USB devices that wants to get
some info from the ACPI).

chip
