Add macros for whitelisting coverity violations. These macros use pragma
directives. The pragma directives and whitelisting macros are only
enabled when a coverity scan is being run.
The whitelisting macros have been added to a new header called
static_analysis.h. The contents of safe_ops.h (CERT C safe ops) have
been moved into static_analysis.h because this will be the new header
for static analysis related macros/defines/etc.

Fix MISRA errors in hal/mm/gmmu/gmmu_gp10b_fusa.c
Rule 10.6 forbids assignment of u32 expression to u64 target.
This patch fixes this rule by casting the expression to u64.
Rule 20.6 doesn't allow use of preprocessor directives within a macro.
To resolve this patch moves the preprocessor directive before the macro
function call.

This patch moves MM HALs that are guaranteed to be functionaly safe
into _fusa.c files. HALs that are not part of FUSA are not compiled
anymore when the safety profile is enabled.
Given a HAL source file:
- it may contain only FUSA code, in that case the source file is
simply renamed with the _fusa postfix.
- it may contain only non-FUSA code, in that case the file is left
as-is
- it may contain a mix, in that case the original file will now only
contain non-FUSA code, and all FUSA code will be moved into a new
source file with the _fusa postfix.

There are many miscellaneous HALs for various MM related functionality.
This patch aims to migrate all the remaining MM code from the <chip>/
mm_<chip>.[ch] files in HAL files under hal/.
Much of this is fairly straightforward copy/paste and updates to the
HAL init files.
The exception to that is the move of the left over gv11b MMU fault
handling code in mm_gv11b.c. Having both a hal/mm/mm/mm_gv11b.c and
a gv11b/mm_gv11b.c file causes tmake to choke so the gv11b/mm_gv11b.c
file was moved to gv11b/mmu_fault_gv11b.c. This will be cleaned up in
a subsequent patch.

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.
