media: i2c: ov5647: use our own mutex for the ctrl lock

Browse Source 
[ Upstream commit 973e42fd5d ]

__v4l2_ctrl_handler_setup() and __v4l2_ctrl_modify_range() contains an
assertion to verify that the v4l2_ctrl_handler::lock is held, as it should
only be called when the lock has already been acquired. Therefore use our
own mutex for the ctrl lock, otherwise a warning will be reported.
