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 v6.11, 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.

In Linux v6.9 the data argument of the function pointer passed to
gpio_device_find() was updated to be a const type. This breaks building
the CDI and ISC drivers for Linux v6.9. Update the test in conftest that
detects the presence of the gpio_device_find() function to perform a
second test to see if the argument for the function pointer is a const
type. Update the drivers that use the gpio_device_find() function
accordingly to fix the build.

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.

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.

Commit 54c86dd20bba ("pwm: Replace PWM chip unique base by unique ID")
removed the 'base' field of the 'pwm_chip' structure replacing it with
an 'id' field. The new 'id' is initialised by the PWM driver core and
does not need to be configured by the PWM drivers.
Add a test for conftest to detect if the 'pwm_chip' structure has the
'base' field and update the various PWM driver to only set this field if
present.

In Linux v6.2, the Tegra IVC driver was updated to support iosys-map and
this breaks building some of the out-of-tree drivers for Linux v6.2+
kernels. In Linux v6.3, the GPIO OF APIs were removed and this breaks
building some of the out-of-tree drivers that use these legacy APIs. For
now the broken drivers are not built for these corresponding kernels.
Instead of checking the kernel version in the Makefile for the
corresponding broken driver, move the kernel version checking to the
top-level Makefile and add CONFIG definitions that can be used the
various Makefiles.
This is also needed for working with 3rd party Linux kernels that may
have upstream backports and need to set these CONFIG variables for their
Linux kernel.
