MISRA Advisory Rule 2.5 states that a project should not contain unused
macro declarations.
While most of the violations in the nvgpu driver are due to unused
macros from hw headers, devinit-related headers, etc. there is a small
number that are due to things like:
* macros not being used when they could/should be
* macros in C files that are really not referenced
* CPP build flag mismatches
This change eliminates such violations from the following:
* replace constants with existing macros in timeout conversion code
* wrap nvgpu_gmmu_dbg macro #defines in #ifdef CONFIG_NVGPU_TRACE/#endif
* wrap MAX_MC_INTR_REGS #define in #ifdef CONFIG_NVGPU_NON_FUSA/#endif
* remove unused FECS_MAILBOX_0_ACK_RESTORE from runlist code
* wrap BACKTRACE_MAXSIZE macro with #ifndef _QNX_SOURCE/#endif

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.

Add support for backtrace prints when BUG() is being called.
To support backtrace calls, the -rdynamic compiler flag is
now being used. On host, it fully works as expected, on
target only exported symbols (in libnvgpu-drv.export) are
visible.
