Xavier Chip Product POR was updated to 20G only. No more qual work
happening for 16G. So we do not plan to support 16G. Now that we have
a single speed left, remove the code added to support nvlink speed from
VBIOS as it is redundant.

Earlier, libnvgpu-drv.so and unit tests were being built with safety
debug profile unconditionally for all qnx and l4t builds.
In order to get coverage numbers corresponding to the release build
let us remove the overriding of the build profile for safety qnx
build. This also needs that these components are built only for
safety qnx and l4t builds.
For x86 and L4T userspace build, default profile is still set to
safety-debug.

As a part of refactoring, we need to move the volt functions from
pmu_pstate.c to volt.c as it belongs there and also move the
arbitor specific functions under CLK_ARB as they will be removed

This patch does the following
*Move volt setup from pmu_pstate to volt
*Move clk freq related functions into CLK_ARB
*Replace pmu.h with nvgpu_mem.h in boardobj.h
*Rename obj_volt to nvgpu_pmu_volt

The atomic counter in interrupt handler can overflow and result in
calling of BUG() which will crash the process. The equivalent
functionality can be implemented with just setting an atomic variable at
start of handler and resetting at end of handler. The wait can be longer
in case there is constant interrupts coming but ultimately it will end.
Generally the wait path is not time critical so it should not be an
issue. Also, fix the unit tests for mc.

Update SW quiesce as follows:
- After waking up sw_quiesce_thread, nvgpu_sw_quiesce
masks interrupts, then disables and preempts runlists
without lock. There could be still a concurrent thread
that would re-enable the runlist by accident. This is
very unlikely and would mean we are not in mission mode
anyway.
- In sw_quiesce_thread, wait NVGPU_SW_QUIESCE_TIMEOUT_MS,
to leave some time for interrupt handler to set error
notifier (in case of HW error interrupt). Then disable
and preempt runlists, and set error notifier for remaining
channels before exiting the process.
Also modified nvgpu_can_busy to return false in case
SW quiesce is pending. This will make subsequent
devctl to fail.
