media: camera: Fix build for Linux v6.8+

Browse Source 
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.
