[PATCH libdrm] tegra: Sync with Linux kernel UAPI header

[PATCH libdrm] tegra: Sync with Linux kernel UAPI header

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

Update the UAPI header to the latest version in the Linux kernel. This
changes the struct drm_tegra_gem_mmap to properly handle offsets on 64-
bit architectures.

See commit bdf765071a8b ("drm/tegra: gem: Return 64-bit offset for
mmap(2)") in the Linux kernel (as of v4.1).

I've taken the liberty of pushing the patch, before we forget about it
(again) :-)
