Current clk unit has multiple header files under include folder.
This has combination of public struct which is accessed outside the

This patch segregates them based on their accessibility.

All public items are moved into include/clk.h which other units can

nvgpu_bios_sw_init was not freeing g->bios on init failure
(for instance when board does not complete devinit).
As a result, the function was skipping init at the next
nvgpu_finalize_poweron attempt. This was resulting in a
crash later on, when attempting to parse VBIOS data.
Changed nvgpu_bios_sw_init to free g->bios and set it to
NULL, in case init fails.

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

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.
