video: camera: Port RTCPU drivers to OOT tree

Browse Source 
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
