This change adds conditional compilation blocks to disable L4T-specific
camera and multimedia drivers when building for embedded Linux platforms.
Key changes include:
- Add ifneq ($(NV_BUILD_SYSTEM_TYPE),embedded-linux) checks in multiple
Makefiles to exclude L4T-specific components
- Introduce NV_IS_L4T define to conditionally include L4T functionality
- Reorganize header includes to support both L4T and embedded Linux builds
- Conditionally wrap L4T-specific struct members and function calls
- Update module dependencies (cdi_mgr now depends on cdi_dev instead of cdi_pwm)

In Linux v6.10, the v4l2-subdev callbacks 'g_dv_timings' and
's_dv_timings' were moved from the v4l2_subdev_video_ops structure to
the v4l2_subdev_pad_ops structure. Fix the build for Linux v6.10 by
using conftest to determine which structure is used for these callbacks.

Add the check to see if the device is already in use or not,
while calling s_ctrl by multiple user apps on the same video node.
Here ,The "vb2_is_busy" function checks if the queue represented
by the vb2_queue instance is busy by checking if there are any
buffers in the active queue.If there are any buffers in the active queue,
it means that they are currently being processed by the device driver,
and the queue is considered busy.

For Linux v6.8, the function strlcpy() has been removed. The function
strscpy() was added in Linux v4.3 and has been preferred over strlcpy().
See upstream Linux commit 30035e45753b ("string: provide strscpy()") for
more details. The Linux checkpatch.pl script warns against using
strlcpy().
The function strscpy() takes the same arguments as strlcpy(), but
returns a type of ssize_t instead of size_t. Update the drivers to use
strscpy() instead of strlcpy().

There is case where CSI channels are initialized later before
accessing it. In this case, it can cause NULL pointer access.
Add checks before accessing it in the function
tegra_channel_find_linked_csi_subdev().

kernel drivers can be built as built-in (=y) or module
(=m). The old ways of checking a driver is enabled or
not is to use "#if define(CONFIG_XXX)" for built-in and
"#if defined(CONFIG_xxx_MODULE)" for module.
Switch to the new IS_ENABLED() macro which can check
a driver is configured as built-in or module.
