tuner: add release callback
From: Michael Krufky <mkrufky@linuxtv.org>
Individual tuner drivers are now allocating memory themselves for
their own private data structures. This changeset adds a release
callback to the tuner operations, so that newer drivers that may
require more complex data structures may release this private data
themselves.
