Subject: [PATCH v3 3/4] media: videodev2.h: add Synaptics tiled modifiers

From: "Hsia-Jun(Randy) Li" <randy.li@...aptics.com>

These modifiers would have the same values as the one defined
in drm_fourcc.h, they would just be named in v4l2 style.

Signed-off-by: Hsia-Jun(Randy) Li <randy.li@...aptics.com>
