From: Paulo Zanoni <paulo.r.zan...@intel.com>
We're adding runtime suspend support to more platforms, so organize
the code in a way that all a new platform needs to do is to add its
own gen-specific functions. Also rename the i915_ functions to intel_
to make it clear that it's the top level one, not something that just
runs on i915 platforms.
