[PATCH v2 0/2] Move TLB invalidation code for its own file and document it

[Mauro Carvalho Chehab <mchehab@kernel.org>]

There are more things to be added to TLB invalidation. Before doing that,
move the code to its own file, and add the relevant documentation.

Patch 1 only moves the code and do some function renames. No functional
change.

Patch 2 adds documentation for the TLB invalidation algorithm and functions.

---

v2: only patch 2 (kernel-doc) was modified:

  - The kernel-doc markups for TLB were added to i915.rst doc;
  - Some minor fixes at the texts;
  - Use a table instead of a literal block while explaining how the algorithm works.
    That should make easier to understand the logic, both in text form and after
    its conversion to HTML/PDF;
  - Remove mention for GuC, as this depends on a series that will be sent later.
