platform: tegra: rtcpu: Implement camera diagnostics driver

Browse Source

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
