intel: Introducing Amber Lake platform

Amber Lake uses the same gen graphics as Kaby Lake, including a id
that were previously marked as reserved on Kaby Lake, but that now is
moved to AML page.

So, let's just move it to AML macro that will feed into KBL macro
just to keep it better organized to make easier future code review
but it will be handled as a KBL.

This is a copy of merged i915's
commit e364672477a1 ("drm/i915/aml: Introducing Amber Lake platform")
