drm/i915: Include i915_gem_evict.c kerneldoc into the drm docbook

Browse source 
I've written these long before we've had a reasonable docbook
structure, and naturally they've gone stale. Fix this up asap.

<title>Buffer Object Eviction</title>
<para>
This section documents the interface function for evicting buffer
objects to make space available in the virtual gpu address spaces.
Note that this is mostly orthogonal to shrinking buffer objects
caches, which has the goal to make main memory (shared with the gpu
through the unified memory architecture) available.
