Conditionally disabled the legacy TEGRA_SYNCPT_INCR IOCTL for T264 platforms since it's no longer needed. This IOCTL is superseded by the newer TEGRA_SYNCPOINT_INCREMENT IOCTL which provides better functionality and follows the modern API design. The conditional compilation helps reduce the attack surface on T264 platforms by removing legacy code paths that aren't needed. Use CONFIG_ARCH_TEGRA_264_SOC as the proper platform-specific flag to identify T264 platforms, as this is the standard architecture flag used throughout the codebase. This change affects: 1. The IOCTL definition in the tegra_drm_ioctls table 2. The IOCTL handler function implementation This improves code cleanliness by removing unnecessary legacy code on newer platforms while maintaining backward compatibility for older platforms that might depend on this IOCTL.
