This fixes MISRA rule 4.7 violations in the function nvgpu_vm_map(). The
violations were caused by trying to use ERR_PTR() to return error
information. Rather than try to return errors in a pointer, just change
the API to return an int and pass the pointer the arguments.

There are many miscellaneous HALs for various MM related functionality.
This patch aims to migrate all the remaining MM code from the <chip>/
mm_<chip>.[ch] files in HAL files under hal/.
Much of this is fairly straightforward copy/paste and updates to the
HAL init files.
The exception to that is the move of the left over gv11b MMU fault
handling code in mm_gv11b.c. Having both a hal/mm/mm/mm_gv11b.c and
a gv11b/mm_gv11b.c file causes tmake to choke so the gv11b/mm_gv11b.c
file was moved to gv11b/mmu_fault_gv11b.c. This will be cleaned up in
a subsequent patch.

Move the remaining GMMU HAL related code from the gm20b/, gp10b/,
and gv11b/ directories to new gmmu hal source files.
Also update all makefiles and HAL init code to refelct the new
location of the headers and source code.

Make a hal/mm/gmmu sub-unit for the GMMU HAL code. Also move the
gk20a specific HAL code there. gp10b will happen in the next patch.
This change also updates all the GMMU related HAL usage, of which
there is quite a bit. Generally the only change is a .gmmu needs to
be inserted into the HAL path. Each HAL init was also updated.

Rename the two native GPU GMMU map/unmap functions and update the
HAL initializations to reflect this:
gk20a_locked_gmmu_map -> nvgpu_gmmu_map_locked
gk20a_locked_gmmu_unmap -> nvgpu_gmmu_unmap_locked
This matches what other units do for handling vGPU "HAL" indirection.
Also move the function declarations to <nvgpu/gmmu.h> since these are
shared among all non-vGPU chips. But since these are still technically
HAL operations they should never be called directly. This is a bit of
an organixational issue that I have not thought through hwo to solve
yet.
Ideally they would go into a "hal/mm/gmmu/" include somewhere, but
that A) doesn't yet exist, and B) those are chip specific; these
functions are native specific. Ugh.

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/.

Add -t/--test-level option for the unit test framework. This
correlates with the test plan levels in GVS. L0 tests are a subset of
the L1 tests. Currently, only test levels 0 and 1 are supported.
The test output has been updated to display skipped tests. Skipped
tests are not included in the test dump.
