HID: steelseries: Manage battery lifetime with refcounting

Browse source

The next change shares one steelseries_device between two HID
interfaces, so the state can outlive either interface. Stop using devm
for it. Reference count the struct with a kref and free it from
steelseries_device_release(). Register and unregister the power supply
explicitly, and clear sd->battery under sd->lock in remove() so it is
not touched after it is unregistered.

Drop the global atomic battery counter and name the power supply after
the device (hdev->uniq, or dev_name() when empty), as hid-input and the
other HID battery drivers do.

No functional change for the current single-interface devices.
