After the error code is checked to be zero, it is possible to return 0
explicitly to help with readability. Also, when available, forward the
return code from the failing function instead of a locally chosen error
code like -EIO.

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
drivers were making exception. This adds the missing log level for video
drivers.
Since all headers had to be modified, this also:
- Update the log initialization to the new syntax from 5e34681
- Sort the #include list to something like #41543

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
memory is required. For example, the PxP and eLCDIF of NXP require aligned
buffers so that their performances can be optimal.

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.

video_mcux_csi_init, which setups the CSI pins (i.e: calls
pinctrl_apply_state) was called after mt9m114_init which tries to do i2c
communication with the camera to read the chip id. But since one of the
CSI pins is the camera master clock, doing things in this order won't
work. This PR inverts the order in which the devices are initialized.
