Since kernel 6.1, merging SYNC_FILE FDs will coalesce
signaled fences into a stub fence - no longer a host1x
fence. To avoid breakage on userspace side, detect such
situations here and instead of returning an error, omit
such fences when processing.

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.

Instead of relying on kernel version to determine if certain functions
or structure are present in the kernel, use the conftest.sh script to
test which functions, structures, etc are present at compile time. This
is beneficial for working with 3rd party Linux kernels that may have
back-ported upstream changes into their kernel and so the kernel version
checks do not work.

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.

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 host1x-fence driver with Linux v6.2. Make the
necessary changes to the host1x-fence driver to fix the build breakage.
