This patch converts the drivers in drivers/media/* to use the
module_i2_driver() macro which makes the code smaller and a bit simpler.

Most users of the <media/soc_mediabus.h> header only need pixel code
definitions, which are now located in the generic <linux/v4l2-mediabus.h>
header. Switch over to reduce soc-camera dependencies.

Remove most trivial uses of struct soc_camera_device from most client
drivers, abstracting some of them inside inline functions. Next steps
will eliminate remaining uses and modify inline functions to not use
struct soc_camera_device.

Now that all soc-camera hosts have been ported to use V4L2 subdevice
mediabus-config operations and soc-camera client bus-parameter operations
have been made optional, they can be removed.

Now that v4l2 subdevices have got their own device objects, having
one more device in soc-camera clients became redundant and confusing.
This patch removes those devices and the soc-camera bus, they used to
reside on.

On suspend, remember whether we are streaming or not, and at what frame format,
so that on resume, we can start streaming again.

This is to avoid needing a forward declaration when ov9740_s_power() (in the
subsequent patch) calls ov9740_s_fmt().

Based on vendor feedback, should issue a software reset at start of day.
Also, OV9740_ANALOG_CTRL15 needs to be changed so the sensor does not begin
streaming until it is ready (otherwise, results in a nonsense frame for the
initial frame).
Added a comment on using discontinuous clock.
Finally, OV9740_ISP_CTRL19 needs to be changed to really use YUYV ordering
(the previous value was for VYUY).

The register width of the ov9740 is 16-bits, so correct the debug print
to reflect this.

This soc_camera driver is for Omnivision's OV9740 sensor. This initial
submission provides support for YUV422 output at 1280x720 (720p), which is
the sensor's native resolution. 640x480 (VGA) is also supported, with
cropping and scaling performed by the sensor's ISP.
This driver is heavily based off of the existing OV9640 driver.
