In Linux v6.8, the 'g_frame_interval' and 's_frame_interval' function pointers were removed from the 'v4l2_subdev_video_ops' structure and replaced by 'get_frame_interval' and 'set_frame_interval' that were added to the 'v4l2_subdev_pad_ops' structure. This change was previously fixed for the Tegra CSI driver by adding the necessary conftest changes. A new update to the Tegra Cam V4L2 causes the build to fail for Linux v6.8+ kernels because of the same issue. Fix up the Tegra Cam V4L2 driver in the same way as the Tegra CSI driver, but update the name of the conftest test to indicate that this is applicable for both the 'get_frame_interval' and 'set_frame_interval' function pointers.
