Mainak Sen f0404e50f6 drm: tegra: Disable TEGRA_SYNCPT_INCR IOCTL for T264 platform ...

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 This IOCTL is superseded by the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.
