With VDLL support the device will request parts of the firmware during
runtime, so instead of releasing the firmware immediately after initial
firmware upload, release it during device deregistration.

FIXME: I am not sure if we run into trouble with the firmware framework
when we don't release the firmware. We might have to copy it over to
some private buffer instead of just keeping it around.

FIXME: we might want to limit the release firmware at remove time to the
devices that actually need it.
