media: i2c: imx290: Use V4L2 subdev active state

Browse source

Use the V4L2 subdev active state API to store the active format. This
simplifies the driver not only by dropping the imx290 current_format
field, but it also allows dropping the imx290 lock, replaced with the
state lock.

The lock check in imx290_ctrl_update() can be dropped as
imx290_set_fmt() can't be called anywmore with which set to ACTIVE
before controls are initialized.
