Add a new sysfs interface that allows toggling camera diagnostics on and
off at runtime without deallocating memory resources. This enhances the
camera-diagnostics driver functionality by:
- Adding a new 'control' sysfs attribute for starting/stopping diagnostics
- Implementing intelligent state checking to avoid unnecessary operations
- Providing better user feedback about the current diagnostic state
- Preserving allocated memory between stop/start cycles
The implementation checks if diagnostics are already running or already
stopped before attempting state changes, preventing redundant operations
and providing informative messages to users.
This allows us to run isp-falcon-memtest, which conflicts with
camera-diagnostics driver.

This commit expands the camera-diagnostics driver to add
support for ISP PFSD tests. The implementation:
- Adds diagnostics IVC communication between kernel and RCE firmware
- Implements ISP SDL test vector loading, verification, and execution
- Provides proper memory allocation and IOMMU mapping across devices
- Supports multiple ISP instances with chip-specific configurations
(T234/ISP6 and T264/ISP7)
- Creates sysfs interface for diagnostic status reporting
- Adds proper error handling and resources cleanup
- Implements CRC validation for test vectors
The driver enables hardware safety diagnostics for camera subsystems
to ensure reliability and functional safety of the camera pipeline.
New header files:
- camrtc-diag-messages.h: Defines messages for IVC communication
- camrtc-diag.h: Contains common diagnostic data structures

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
