Alex Waterman 3a764030b1 gpu: nvgpu: Add new mm HAL and move cache code to that HAL ...

Add a new MM HAL directory to contain all MM related HAL units.
As part of this change add cache unit to the MM HAL. This contains
several related fixes:

1. Move the cache code in gk20a/mm_gk20a.c and gv11b/mm_gv11b.c to
   the new cache HAL. Update makefiles and header includes to take
   this into account. Also rename gk20a_{read,write}l() to their
   nvgpu_ variants.

2. Update the MM gops: move the cache related functions to the new
   cache HAL and update all calls to this HAL to reflect the new
   name.

3. Update some direct calls to gk20a MM cache ops to pass through
   the HAL instead.

4. Update the unit tests for various MM related things to use the
   new MM HAL locations.

This change accomplishes two architecture design goals. Firstly it
removes a multiple HW include from mm_gk20a.c (the flush HW header).
Secondly it moves code from the gk20a/ and gv11b/ directories into
more proper locations under hal/.
