[PATCH] video: mmp: drop needless devm cleanup

["Uwe Kleine-König" <u.kleine-koenig@pengutronix.de>]

The nice thing about devm_* is that the driver doesn't need to free the
resources but the driver core takes care about that. This also
simplifies the error path quite a bit and removes the wrong check for a
clock pointer being NULL.
