[PATCH libdrm 15/25] tests: tegra: Add gr2d-fill test

[Thierry Reding <thierry.reding@gmail.com>]

From: Thierry Reding <treding@nvidia.com>

This test uses the IOCTLs for job submission and fences to fill a sub-
region of the screen to a specific color using gr2d.

Signed-off-by: Thierry Reding <treding@nvidia.com>
