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 This IOCTL is superseded by the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.

The following functions are exported from nvmap code and being used by
nvgpu in non-DriveOS code like L4T. Hence we should not include these
functions in embedded builds.
- nvmap_get_vpr_dev
- nvmap_get_vpr1_dev
The following functions get used in DriveOS as well by nvmap, but no
need to export to nvgpu, as they are not supposed to be used on DrivOS
by other modules. Hence do not export this in embedded builds.
- nvmap_dma_alloc_attrs
- nvmap_dma_free_attrs
In order to achieve this, define a new config file for embedded-linux
and define config and ccflag which can be used in any OOT driver to
differentiate between embedded-linux and non embedded-linux builds.
