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.

Upstream Linux commit 4c1e0a97351a ("firmware: tegra: bpmp: Use
iosys-map helpers") updated the Tegra IVC driver to use the
iosys-map helpers for Linux v6.2. This causes the Tegra capture-ivc
driver build to fail. Temporarily disable the building of this driver
while this build issue is fixed. Stub functions are added to permit
other drivers that use this driver to build.

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.

The RTCPU driver fails to build with Linux v5.14 as an out-of-tree
module because the return type of the bus_type remove callback is int
and not void. Make the necessary changes to allow the RTCPU driver to
build for Linux v5.14+ kernels.

Port RTCPU drivers from kernel/nvidia to kernel/nvidia-oot.
In addition to copying the files this patch:
1) Modifies make files to build rtcpu drivers as modules
2) Modifies licenses of all ported files to SPDX
3) Adds MODULE_LICENSE macro to all modules
4) Removes checks for old kernel versions and the dead code after those checks
5) Fixes style errors according to checkpatch.pl
