drm/i915: replace IS_GEN and friends with GRAPHICS_VER

This was done by the following semantic patch:

	@@ expression i915; @@
	- INTEL_GEN(i915)
	+ GRAPHICS_VER(i915)

	@@ expression i915; expression E; @@
	- INTEL_GEN(i915) >= E
	+ GRAPHICS_VER(i915) >= E

	@@ expression dev_priv; expression E; @@
	- !IS_GEN(dev_priv, E)
	+ GRAPHICS_VER(dev_priv) != E

	@@ expression dev_priv; expression E; @@
	- IS_GEN(dev_priv, E)
	+ GRAPHICS_VER(dev_priv) == E

	@@
	expression dev_priv;
	expression from, until;
	@@
	- IS_GEN_RANGE(dev_priv, from, until)
	+ IS_GRAPHICS_VER(dev_priv, from, until)

	@def@
	expression E;
	identifier id =~ "^gen$";
	@@
	- id = GRAPHICS_VER(E)
	+ ver = GRAPHICS_VER(E)

	@@
	identifier def.id;
	@@
	- id
	+ ver

It also takes care of renaming the variable we assign to GRAPHICS_VER()
so to use "ver" rather than "gen".
