drm/i915: Separate cherryview from valleyview
The cherryview device shares many characteristics with the valleyview
device. When support was added to the driver for cherryview, the
corresponding device info structure included .is_valleyview = 1.
This is not correct and leads to some confusion.
This patch changes .is_valleyview to .is_cherryview in the cherryview
device info structure and simplifies the IS_CHERRYVIEW macro.
Then where appropriate, instances of IS_VALLEYVIEW are replaced with
IS_VALLEYVIEW || IS_CHERRYVIEW or equivalent.
v2: Use IS_VALLEYVIEW || IS_CHERRYVIEW instead of defining a new macro.
Also add followup patches to fix issues discovered during the first
review. (Ville)
v3: Fix some style issues and one gen check. Remove CRT related changes
as CRT is not supported on CHV. (Imre, Ville)
v4: Make a few more optimizations. (Ville)
