V4L2_CID_TEST_PATTERN is now a standard control.
This patch replaces the user defined control for test
pattern to make use of standard control V4L2_CID_TEST_PATTERN.

Compute the horizontal blanking value according to the datasheet. The
value written to the hblank and vblank registers must be equal to the
number of blank columns and rows minus one.

Add four new controls to configure black level compensation (BLC):

- V4L2_CID_BLC_AUTO selects between manual and auto BLC
- V4L2_CID_BLC_TARGET_LEVEL sets the target level for auto BLC
- V4L2_CID_BLC_ANALOG_OFFSET sets the analog offset for manual BLC
- V4L2_CID_BLC_DIGITAL_OFFSET sets the digital offset for manual BLC

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

The MT9P031 and MT9T001 sensors transfer 16-bit data on the I2C bus in
swapped order. Let the I2C core handle byte order by using the
i2c_smbus_{read|write}_word_swapped() functions.

Both mt9t001.c and mt9p031.c have two identical issues, those
being that they will need module.h inclusion for the upcoming
cleanup going on there, and that their dependencies don't limit
selection of configs that will fail to compile as follows:

The related config options are CONFIG_MEDIA_CONTROLLER and
CONFIG_VIDEO_V4L2_SUBDEV_API.  Looking at the code, it appears
that the driver was never intended to work without these enabled,
so add a dependency on CONFIG_VIDEO_V4L2_SUBDEV_API, which in
turn already has a dependency on CONFIG_MEDIA_CONTROLLER.

The MT9P031 is a parallel 12-bit 5MP sensor from Aptina (formerly
Micron) controlled through I2C.

The driver creates a V4L2 subdevice. It currently supports skipping,
cropping, automatic binning, and gain, exposure, h/v flip and test
pattern controls.
