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/.

gv11b_mm_l2_flush was not checking error codes from the various
functions it was calling. MISRA Rule-17.7 requires the return value
of all functions to be used. This patch now checks return values and
propagates the error upstream.

Local golden image is copy of global GR context buffer hence move its
ownership to global context unit
Add new structure nvgpu_gr_global_ctx_local_golden_image to hold all meta
data for local golden image and move it to struct gr_gk20a
Expose and use new APIs to initialize/deinitialize and load local golden image

Current code creats golden image using dedicated gr_ctx called
GOLDEN_CTX. But on RM server it's no easy to create a GOLDEN_CTX since
virtual addresses are managed by guest OSes. There's no special reason
why we have to use a separate gr_ctx for golden image. This patch moves
it to use current channel gr_ctx. And the function will be re-useable
by RM server.

Add new unit common/gr/global_ctx.c to manage GR global context buffers
This unit provides interfaces to allocate/free/map/unmap all the global
context buffers. It also provides APIs to get/set size of the buffers,
and to get memory handle of the buffers
Use interfaces exposed by this unit instead of directly accessing global
context buffers in common code
Add new header file include/nvgpu/gr/global_ctx.h to declare all the
interfaces.
Rename "struct gr_ctx_buffer_desc" to "struct nvgpu_gr_global_ctx_buffer_desc"
which holds all data for each global context
Remove void *priv since it is no longer used
Add size to the desc structure to store the requested size
Remove global_ctx_buffer_size from struct nvgpu_gr_ctx since it is no longer
used for any real purpose
