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 but yet as alpha_support. On following patches we will start adding PCI IDs and the platform specific changes. CNL has an increased DDB size as Damien had previously noticed and provided a separated patch that got squashed here. v2: Squash DDB size here per Ander request.
