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.

In Linux v6.11, commit d6f66e292676 ("pwm: Make pwm_request_from_chip()
private to the core") made the function pwm_request_from_chip() a
private function to the PWM core driver. This function is used by both
the CDI and ISC camera drivers and so these driver no longer build
against Linux v6.11.
Fix this by updating the CDI and ISC drivers to use the function
of_pwm_xlate_with_flags() which has been supported since Linux v3.8.
This function internally calls pwm_request_from_chip() and configures
the pwm->args.period parameter and is therefore, equivalent to the
existing code.

Upstream commit 690da22dbfa8 ("asm-generic/io.h: kill vmalloc.h
dependency") removed the vmalloc.h header file from io.h and this breaks
building various drivers with the latest -next kernels. Fix this
by ensuring vmalloc.h is included and in most cases slab is not actually
needed and so remove this where possible. Note that it is fine to make
this change for all current supported kernels.

When adding conftest tests for detecting if specific functions are
present, it is always better to check if the newly added function is
present versus the function that has been removed. The reason being that
is the newly added function is modified in the future then the conftest
tests can be extended to check for updates to the function.
Therefore, instead of checking if the function gpiochip_find() is
present, which was removed in Linux v6.7, check if the function
gpio_device_find() is present, which replaced gpiochip_find in Linux
v6.7.

Kernel freeze is occurring due to incorrect cleanup
in vi5.c.
Fix for kernel freeze:
1 Don't call vi_channel_drv_unregister() and
tegra_vi_media_controller_cleanup() in vi5_remove.
2 capture_vi_probe() is calling vi_channel_drv_register() and
tegra_capture_vi_media_controller_init(), so capture_vi_remove()
should call vi_channel_drv_unregister() and
tegra_vi_media_controller_cleanup()
3 Use correct dev pointer in vi_channel_drv_unregister().
Code cleanup:
1 Remove use_legacy_path variable that was used for T186.
2 Removed unused t194_vi5_file_private struct.

The 'of_pwm_n_cells' has been removed from the pwm_chip structure in the
latest linux-next development branch that will eventually become Linux
v6.9. This parameter was used in function 'of_pwm_xlate_with_flags'.
The camera CDI and ISC drivers don't use the kernel's
of_pwm_xlate_with_flags xlate function and instead implement their own
xlate function. Therefore, it is safe to simply drop the usage of the
'of_pwm_n_cells' parameter completely in these drivers.

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().

For reference, the changes in core kernels are:
