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.

Instead of relying on kernel version to determine if the 'remove'
callback for the 'bus_type' structure return an integer or void, add a
compile time test to the conftest.sh script to determine this at compile
time for the kernel being used. 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.

The RTCPU driver has a dependency of the following kernel modules:
clk-group
device-group
reset-group
Rather that builds all these source files as individual drivers, which
is bloating the number of kernel modules required, compile these source
files into the main RTCPU kernel module.
Finally, remove any unneeded header files from the ivc-bus driver.

For dma mappings done with dma_map_sg() calls, dma_sync_sg* calls are
required in order to make sure that caches for all the scattered
addresses are synced. Using dma_sync_single* call for syncing caches
can access address which is not mapped by dma_sync_sg() and cause kernel
exceptions.
Fix this by using correct cache sync calls for appropriate dma mapping
APIs.
