Add SMARTDMA video driver. This driver uses the SMARTDMA engine as a
parallel camera interface, which can read QVGA frames from a camera
device. Due to SRAM constraints, the video driver divides the camera
stream into multiple horizontal video buffers as it streams them back to
an application.

Improve resolution init code for OV7670 driver, to properly program the
full set of registers needed to realize a given output resolution. The
settings for these registers are based on those used in the MCUX SDK
driver, which are derived from the resolution register settings given in
the OV7670 programming guide, with a different configuration for the
CLKSRC and DBLV registers used for the input clock.

While applying the format, the pixel format and drv_data->fmt were set
immediately, and the resolution was set only if it had a matching
entry on the "caps".
This commit makes sure the requested format matches the caps before
applying the format as well as drv_data->fmt. This does not guards
against partial failure (i.e. only pixelformat set and not
resolution).

Zephyr drivers have typically one log level defined per class. The video

On i.MX RT11XX which has MIPI CSI-2 Rx, image data from the camera sensor
after passing through the camera pipeline (MIPI CSI-2 Rx --> Video Mux -->
CSI) will be implicitly converted to a 32-bits pixel formats. For example,
an input in RGB565 / YUYV (2-bytes format) will become an XRGB32 / XYUV32
(4-bytes format), respectively. Make changes to support this.

The CSI should always propagate the get_fmt request down to the sensor.
It should not return a format by it own unless it contains a test
pattern generator inside it.
The problem with the legacy code is that this code snippet is never
reached if the sensor could return a format. In case the sensor failed
to return a format, these codes are reached but the returned format
makes no sense and its value was not initialized.

For some hardwares, it is very common that some aligment on the allocated

Currently, the driver supports only VGA resolution while 480x272 is
needed to match with the display resolution on i.MX RT10XX family.
Also, the current framerate is very low, about 3-4 fps without doing
anything else with the image buffers (just discarding them).
Rework the driver to address the low framerate issue as well as to add
support for 480x272 and 1280x720 resolutions.
