[Intel-gfx] [PATCH i-g-t 1/5] lib/cnl: Introduce Cannonlake platform defition.

[Rodrigo Vivi]

Cannonlake is a Intel® Processor containing Intel® HD Graphics
following Kabylake.

It is Gen10.

Let's start by adding the platform definition based on previous
platforms.

On following patches we will start adding PCI IDs and the
platform specific changes.
