``VIDEO_PIX_FMT_GRBG8`` becomes ``VIDEO_PIX_FMT_SGRBG8``
``VIDEO_PIX_FMT_RGGB8`` becomes ``VIDEO_PIX_FMT_SRGGB8``

* On STM32 devices, the DCMI driver (:dtcompatible:`st,stm32-dcmi`) now relies on endpoint based
video-interfaces.yaml bindings for sensor interface properties (such as bus width and
synchronization signals).
Also the ``capture-rate`` property has been replaced by the usage of the frame interval API
:c:func:`video_set_frmival`.
See (:github:`89627`).
