The em28xx driver only calls subdevices' .s_power() method to power them down, relying on the hardware to wake up automatically, which is usually the case with tuners. This was acceptable with the old .standby() method, but is wrong with .s_power(). Fixing the driver would be difficult due to a broad supported hardware base. Instead this patch makes use of the unbalanced_power soc-camera subdevice flag to tell the ov2640 driver to balance calls to v4l2_clk_enable() and v4l2_clk_disable() internally.
