Application can query information about a control given the control id,
the framework fill the rest of the structure. Application can also
enumerate all kinds of device's supported controls by iterating with
VIDEO_CTRL_FLAG_NEXT_CTRL on the same API.

Implement the video control framework with the following features:
- Drivers initialize the control with a valid value range at boot which
guides the application developer and the framework. Hence, the video
framework could do all common works for drivers e.g., sanity check.
- Controls need to be cached to memory. Video framework handles
get_ctrl(), drivers don't need to implement this API. It is because
reading control value directly from registers are not only inefficient
but also sometimes impossible, e.g. controls that scatter through
several registers. Only "volatile" control needs to be updated at
runtime.
- Only the devices (e.g., sensors) owning the controls need to
implement set_ctrl(). Other devices of the pipeline do not need to
propagate set_ctrl() and hence, do not need to implement this API

A macro introduced allows to log four-character-codes (FOURCC) as one
string instead of enumerating each individual character. This saves a bit
of room in the code and is less error-prone.

Rename video_fourcc() to VIDEO_FOURCC(), differing from the Linux
implementation, but more compliant with the coding style.
Also introduce a VIDEO_FOURCC_FROM_STR() to generate a FOURCC format
code out of a 4-characters string.

Do hflipping at camera level to avoid using PxP which impacts camera
framerates on RT10xx. Moreover, on RT11xx, PxP is already reserved
for 90 CCW image rotation.

Add an option to mirror the video image horizontally. This helps
to avoid doing so at the post-processing step by using additional
HW such as PxP on i.MX RT platforms.

Currently, the camera fixture test can only tell whether data are dumped
onto memory. This is to check further if the image content is correct.
The algorithm is rather simple: compare the average color of each bar
of a generated pattern with a predefined target in CIELAB76 color
space (which is nearly perceptually uniform).

The logs that the fixture test are based on are not printed anymore due
to recent changes from "printk" to "LOG_DBG". Change the log level so
that it can work again.
Remove "Capture started" as it is not a relevant test regex. Logs are
sometimes not correctly printed in the console, for example, we can see:
DEBUG - DEVICE: muart:~$ [mapture started
As "Capture started" is a one-time log, fixture test will then fail due
to timeout.
Also, consolidate other regex.
