[0/2] Splitting intel-gtt calls for non-x86 platforms

Message

Bowman, Casey G March 19, 2022, 2 a.m. UTC

The intel-gtt module defines some functions used by i915, but they are
only supported by x86 platforms. In order to bring i915 to a more
arch-neutral state, we split out these functions and provide stubs in
the case of non-x86 builds.

There may be a better filename choice for the files used in splitting
the calls, it's very much open to discussion.
