This camera driver supports only rising edge, which is the default
setting of the device. The function mt9m111_setup_pixfmt() overwrites
this setting. So the driver actually uses falling edge.
This patch corrects that.

The setup of the pixel clock is done wrong in the mt9v022 driver.
The 'Invert Pixel Clock' bit has to be set to 1 for falling edge
and not for rising. This is not clearly described in the data
sheet.

Tested on pcm037 and pcm027/pcm990.

12-bit formats, similar to YUV 4:2:0 occupy 3 bytes for each two pixels
and cannot be described by any of the existing SOC_MBUS_PACKING_* macros.
This patch adds a new one SOC_MBUS_PACKING_1_5X8 to describe such
formats and extends soc_mbus_samples_per_pixel() to support it.

Since V4L2_MBUS_FMT_* codes have become large and sparse, they cannot

Recently mediabus pixel format codes have become a part of the user-
space API, at which time their values also have been changed from
contiguous numbers, running from 0 to sparse numbers with values
around 0x1000, 0x2000, 0x3000... This made them unsuitable for the
use as array indices. This patch switches soc-camera internal format
look-ups to not depend on values of those macros.

This ioctl extends UVCIOC_CTRL_GET/SET by not only allowing to get/set

namely GET_CUR, SET_CUR, GET_MIN, GET_MAX, GET_RES, GET_LEN, GET_INFO
and GET_DEF. This is required for applications to work with XU controls,
so that they can properly query the size and allocate the necessary
buffers.

The initial version of this patch (commit
d5976931639176bb6777755d96b9f8d959f79e9e) had some issues:

 * It didn't correctly calculate the size of the YUV buffer for 4:2:2,
   resulting in capture sometimes being offset by 1/3rd of a picture.

 * There were a lot of variables duplicating information the driver
   already knew, which have been removed.

 * There was an in-kernel format conversion - libv4l can do this one,
   and is the right place to do format conversions anyway.

 * Some magic numbers weren't properly explained.

Fix all these issues, leaving just the move from videobuf to videobuf2
to do.
