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

Cleanup issues with traceability for common.mc:
- Move these declarations under macros or @cond as they are either
non-fusa or private functions to the unit:
- gm20b_mc_is_enabled
- mc_gp10b_log_pending_intrs
- mc_gp10b_ltc_isr
- gv11b_mc_is_intr_hub_pending
- Fix typo in SWUTS for gv11b_mc_is_stall_and_eng_intr_pending

Previously, unit interrupt enabling/disabling and corresponding MC level
interrupt enabling/disabling was not done at the same time.
With this change, stall and nonstall interrupt for units are programmed
at MC level along with individual unit interrupts. Kept access to MC
interrupt registers through mc.intr_lock spinlock.
For doing this separated CE and GR interrupt mask functions.
mc.intr_enable is only used when there is global interrupt
control to be set. Removed mc_gp10b.c as mc_gp10b_intr_enable
is now removed. Removed following functions - mc_gv100_intr_enable,
mc_gv11b_intr_enable & intr_tu104_enable. Removed intr_pmu_unit_config
as we can use the generic unit interrupt control function.

gk20a.h will include gops_mc.h to contain the mc ops definitions. Add
doxygen comments for the HAL functions that are called directly.
Also move mc_gp10b_intr_pmu_unit_config to non-fusa HAL file.

Rule 8.6 requires each identifier with external linkage to have exactly
one external definitions.
Rule 10.x necessitates operands to have essential type; left and right
operands should be of same width and type.
Rule 17.7 requires function return value to be checked for error
information.
This patch fixes above mentioned errors in nvgpu.hal.mc.

pmu_gk20a.c includes hw_mc_gk20a.h other than hw_pwr_gk20a.h
to access & configure pmu interrupt, this breaks single hw header
for HAL file.
Moved PMU interrupt enable to MC unit by creating/modifying current
mc ops intr_unit_config to intr_pmu_unit_config to configure PMU
interrupt specifically as this ops is only used by PMU unit
