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

This patch adds kms_nv12 test case. It covers testing NV12
in linear/tile-X/tile-Y tiling formats in 0/90/180/270
orientations. For each tiling format, it tests several
combinations of planes and its scaling.

v2:
-Added 90/270 tests (me)
-took out crc test as it isn't adding much value due to chroma upsampling (me)

v3:
-Make --list-subtests option work (Tvrtko)
-Make nv12 unsupported test run properly either as a sub test
 or along with all other tests (me)
-Added nv12 fb with invalid params (Daniel)

For such simple invalid input paramaters tests the usual approach is to
split them out. Also you don't have to do a modeset for addfb (which will
speed things up). Essentially each block with an igt_assert should be its
own subtest.

If each block is split into it's own subtest, if one runs just a subtest 
and without a modeset, I don't know in which state the system is to start
the test and doing a modeset will start with a known state.

ADDFB ioctl doesn't need any known modeset state at all, and that seems to
be the only ioctl you do. Which means you really don't need to do a
modeset (it's just overhead). See e.g. the other addfb testcases we have
in kms_addfb_basic.c.
