Johan Hovold 36602a2981 greybus: module: implement controlled module removal ... Implement controlled module removal through a new module attribute "eject". When a non-zero argument is written to the attribute, all interfaces of the module are disabled (e.g. bundles are deregistered) and deactivated (e.g. powered off) before instructing the SVC to physically eject the module. Note that the module device is not deregistered until the SVC has reported the physical removal of all of its interfaces. A new interface mutex is added to enforce interface state-change serialisation.
