Cherryview (CHV) is the latest Intel(r) Atom(tm) Processor from Intel
containing Intel(r) HD Graphics.

The major GPU hardware features include:
- Gen8 Intel(r) HD Graphics graphics
- three display pipes
- three HDMI/DP/eDP display ports
- two MIPI DSI display ports
- removal of VGA support

This series exposes the basic features for CHV, bringing us to roughly
feature parity with earlier platforms.

The GT side programming follows the path laid out by Broadwell, so the
number of patches dealing with GT functionality is fairly low. By far
the largest amount of new code is added to deal with the new DP/HDMI
display PHY, and the third display pipe. The RC6 and turbo changes were
also fairly substantial.

Big thanks to everyone who contributed! In particular to Chon Ming for
the display PHY support and to Deepak for the RC6 and turbo support.
