[PATCH 02/11] media: adv7180: Add missing lock in suspend callback

["Niklas Söderlund" <niklas.soderlund+renesas@ragnatech.se>]

The adv7180_set_power() utilizes adv7180_write() which in turn requires
the state mutex to be held, take it before calling adv7180_set_power()
to avoid tripping a lockdep_assert_held().
