- "include/trace/events/gk20a.h" file was having GPL2 license
(which should not used for QNX code). This file was used for
compiling linux userspace driver("libnvgpu-drv.so") and was used for
unit testing on QNX.
- This patch removes stubs in "include/trace/events/gk20a.h" file.
(which were used for linux userspace driver.)
- For QNX driver, "nvgpu_rmos/trace/events/gk20a.h" was used.
This patch moves that file to "include/nvgpu/posix/trace_gk20a.h" and
does relevant license change. This same file will be used for linux
userspace driver.
- This patch also creates a new file "include/nvgpu/trace.h" which
selects proper trace file depending on the config.

Advisory Rule 2.7 states that there should be no unused
parameters in functions.
This patch removes unused function parameters from the following:
* release_as_share_id() -> remove 'id' param
* nvgpu_pd_cache_look_up() -> remove 'g' param
* nvgpu_vm_get_pte_size_fixed_map() -> remove 'size' param

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.

The container_of() macro used in nvgpu produces the following
set of MISRA required rule violations:
* Rule 11.3 : A cast shall not be performed between a pointer to
object type and a pointer to a different object type.
* Rule 11.8 : A cast shall not remove any const or volatile
qualification from the type pointed to be a pointer.
* Rule 20.7 : Expressions resulting from the expansion of macro
parameters shall be enclosed in parentheses
Using the same modified implementation of container_of() as that
used in the nvgpu_list_node/nvgpu_rbtree_node routines eliminates
the Rule 11.8 and Rule 20.7 violations and exchanges the Rule 11.3
violation with an advisory Rule 11.4 violation.
This patch uses that same equivalent implementation in two new
(static) functions that are used to replace references to
container_of() references in vm.c:
* nvgpu_mapped_buf_from_ref
* vm_gk20a_from_ref
The implementation of the following routine has also been updated
using the same approach to eliminate the direct reference to
container_of():
* gk20a_from_as
It should be noted that replacement functions still contain
potentially dangerous (and non-MISRA compliant code) and that it is
expected that deviation requests will be filed for the new advisory
rule violations accordingly.
