The sensor starts streaming video as soon as it gets powered or is
reset. Disable the output in the reset function.

Conversion from i2c_client to ov772x_priv is only needed in a single
location, while conversion from v4l2_subdev to ov772x_priv is needed in
several locations. Perform the former manually, and use to_ov772x for
the later.

If the requested format isn't supported, return a fixed default format
instead of the current format.

The format and window size are only initialized during the first g_fmt
call. This leaves the device in an inconsistent state after
initialization, which will cause problems when implementing pad
operations. Move the format and window size initialization to probe
time.

Several client drivers access the hardware at probe time, for instance
to read the probe chip ID. Such chips need to be powered up when being
probed.
soc-camera handles this by powering chips up in the soc-camera probe
implementation. However, this will break with non soc-camera hosts that
don't perform the same operations.
Fix the problem by pushing the power up/down from the soc-camera core
down to individual drivers on a needs basis.

Instead of forcing all soc-camera drivers to go through the mid-layer to
handle power management, create soc_camera_power_[on|off]() functions
that can be called from the subdev .s_power() operation to manage
regulators and platform-specific power handling. This allows non
soc-camera hosts to use soc-camera-aware clients.
