drm/i915/glk: Introduce Geminilake platform definition

Geminilake is an Intel® Processor containing Intel® HD Graphics
following Broxton.

Let's start by adding the platform definition. PCI IDs and plaform
specific code will follow.

v2: Rebase (don't allow dev to be used with the new macro).

v3: Update ddb size. (Matt)
    Rebase on s/preliminary_hw/alpha/
