Subject: [PATCH v3 0/9] Add HSV format

HSV formats are extremely useful for image segmentation. This set of
patches makes v4l2 aware of this kind of formats.

Vivid changes have been divided to ease the reviewing process.

We are working on patches for Gstreamer and OpenCV that will make use
of these formats.

We still need to decide if and how we will support HUE range 0-255


Changelog:
v3:  Fix wrong handling of some YUV formats when brightness != 128

Suggested by Laurent Pinchart <laurent.pinchart@...asonboard.com>

Suggested by Hans Verkuil <hverkuil@...all.nl>
-Rebase over master and docs-next
-Introduce TPG_COLOR_ENC_LUMA for gray formats
