media: atomisp: ov2722: Power on sensor from set_fmt() callback

Browse source

Depending on which order userspace makes various v4l2 calls, the sensor
might still be powered down when set_fmt is called.

What should really happen here is delay the writing of the mode-related
registers till streaming is started, but for now use the same quick fix
as the atomisp_ov2680 / atomisp_gc0310 code and call power_up() from
set_fmt() in combination with keeping track of the power-state to avoid
doing the power-up sequence twice.
