media: camera: Fix build for Linux v6.8

Browse Source 
In Linux v6.8, the 'g_frame_interval' function pointer was removed from
the 'v4l2_subdev_video_ops' structure and replaced by
'get_frame_interval' that was added to the 'v4l2_subdev_pad_ops'
structure. Add a test to conftest to detect if 'get_frame_interval' is
supported and update the camera CSI driver accordingly to populate the
appropriate function pointer.

Note that the new 'get_frame_interval' function pointer has an
additional 'state' argument but is otherwise the same as the previous
'g_frame_interval' function pointer.
