[PATCH i-g-t 2/2] tests/test_nv12.c: This patch adds test_nv12 test case. It is a simple test that covers testing NV12 in linear/tile-X/tile-Y tiling formats.

[Vidya Srinivas <vidya.srinivas@intel.com>]

From: chandra konduru <chandra.konduru@intel.com>

Previous version reference https://patchwork.freedesktop.org/patch/59067/
was posted by Chandra Konduru on Sept 9 2015 based on the
IGT framework available at that time

Current version: Rebased as per current IGT (me).
This version tests basic NV12
in linear/tile-X/tile-Y tiling formats.
