[PATCH libdrm 02/25] tegra: Remove unused IOCTL implementations

[Thierry Reding]

From: Thierry Reding <treding at nvidia.com>

The DRM_TEGRA_GEM_{GET,SET}_FLAGS and DRM_TEGRA_GEM_{GET,SET}_TILING
IOCTLs were badly designed and have since been obsoleted by framebuffer
modifiers. Remove these implementations to make it clear their usage is
discouraged.
