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.

In Linux v6.4, the module pointer argument is removed from the
class_create() function. Add a test to the conftest script that checks
if this argument for the class_create() function has been removed and
use the definition created by conftest to select which version of the
function is used.

Remove the module pointer from the class_create() based
on following change in core kernel
======
driver core: class: remove module * from class_create()
The module pointer in class_create() never actually did anything, and it
shouldn't have been requred to be set as a parameter even if it did
something. So just remove it and fix up all callers of the function in
the kernel tree at the same time.

Camera fsync signal Driver provides following features.
- Configures and runs TSC generator to provide fsync signal to the
camera module
- FSYNC signal is programmed as specified in DT for freq and offset
- Start time of fsync signal can be specified or default
value can be used
- Default value used will be 10ms in future
- If start time is provided, value must be provided in TSC ticks unit
- Read DT, if tsc-gen-groups are specified, init & expose node for
each group
- Each generator in group is configured
- IOCTL interface is exposed to accept start time and start the generator
- Sanity check is done to ensure, no generator is part of multiple groups
- Backward compatibility is maintained

Add support for configurable interrupt timers and event notification
queues to SIPL Device Block to mirror the CDAC (QNX) pulse channel
interface.
The CDI_MGR_IOCTL_INTR_CONFIG IOCTL is added to set the timeout
duration at initialization, and existing GPIO interrupt code is
refactored.
Also removes the GPIO index limitation to the range of [0,31] by
returning the complete indices one at a time instead of a bit flag.

When kernel command line debugfs=off is specified instead of
disabling CONFIG_DEBUG_FS in defconfig to disable Debug-FS,
debugfs functions like debugfs_create_dir will fail.
Use function debugfs_initialized() to check if debugfs
functionality is enabled before calling any debugfs functions.
This allows us to by-pass debugfs initialization if debugfs
is not enabled.

Upstream Linux kernel commit ff62b8e6588f ("driver core: make struct
class.devnode() take a const *") updated the 'devnode' function pointer
under the class structure to take a const device struct. This breaks
building the Tegra CDI MDR driver with Linux v6.2. Make the
necessary changes to the CDI MGR driver to fix the build breakage.
Also update CDI MGR GPIO code since devm_fwnode_get_gpiod_from_child()
is deprecated in Linux v6.2. Switch to use devm_fwnode_gpiod_get_index()
for Linux v6.2.
