media: i2c: ov5648: Fix lockdep error
ov5648_state_init() calls ov5648_state_mipi_configure() which uses
__v4l2_ctrl_s_ctrl[_int64](). This means that sensor->mutex (which
is also sensor->ctrls.handler.lock) must be locked before calling
ov5648_state_init().
ov5648_state_mipi_configure() is also used in other places where
the lock is already held so it cannot be changed itself.
Note this is based on an identical (tested) fix for the ov8865 driver,
this has only been compile-tested.
