Currently, the SDCA code registers the HID device whilst parsing the DisCo information. This necessitates storing the HID device in the DisCo structs, which are intended to only store the parsed DisCo. Having the HID device registered so early in the process also causes some issues with cleaning up. Update the code to register the HID device as the IRQs are handled, this alleviates the previous concerns and brings the support inline with the other SDCA event handling. As part of this move the naming for the SDCA HID is also updated, it saves some complexity around the passing of the SoundWire device to include this in this patch. Update to using the dev_name for the phys, which is more consistent with other HID users, and use the actual function name/address for the HID name itself.
