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.

This patch reverts the following commit 13a7ef2cc7
The bios devinit for tu104 encountered the unaligned buffer scenario.
However bios devinit functionality is now removed from nvgpu. Other
than that there are no firmwares where we expect the input/output
buffer addresses to be un-aligned, hence removing the logic added
to handle un-aligned addresses.

This patch moves all the safe static and non-static functions as well
as its dependencies such as static declared structs into files with
_fusa.c extension. If the original file is left with no functions
remaining then the file is deleted.
Added changes in Makefile, Makefile.sources, nvgpu-hal-new.yaml for
compilation.

Shortcomings of ALIGN macros:
- ALIGN_MASK down aligns when there is an wrapping/overflow instead of
throwing an error. This can affect the size assumptions.
- Alignment a's check will be bypassed when ALIGN_MASK is directly
used.
Fix these issues by 1) adding compile time error for non-unsigned type
arguments 2) using unsigned type safe ops for addition and subtraction.
Also, change users of ALIGN to pass unsigned types only.

Function for copying to/form IMEM/DMEM cast pointer to char to
pointer to u32 since falcon data registers are read/written in
4-bytes. Firmware data is generally byte stream and hence we
won't be able to deal in pointer to u32. Hence we need deviate
from misra rule 11.3.
Firmware data is also not aligned at word boundary sometimes
hence we need to copy it byte by byte to conform to the dev-
iation recommendation.
Error: MISRA C-2012 Rule 11.3: ./hal/falcon/falcon_gk20a.c:296:
misra_violation: The object pointer expression "src" of type
"u8 *" is cast to type "u32 *".
