Coffee Lake is a Intel® Processor containing Intel® HD Graphics
following Kabylake.
It is Gen9 graphics based platform on top of CNP PCH.
Let's start by adding the platform definition based on previous
platforms but yet as preliminary_hw_support.
On following patches we will start adding PCI IDs and the
platform specific changes.
