93ebeac3bd gpu: nvgpu: mm: fix CERT-C bugs in nvgpu.*.mm.mm
INT-30 requires checking for overflow of arithmetic operations on
unsigned integers.
INT-31 requires bounds checking for unsigned integers cast to
smaller size.

Fix these violations by using the safe ops in nvgpu.common.mm.mm and
nvgpu.hal.mm.mm.

9a4ad88f21 gpu: nvgpu: hal: split MM-related HALs based on FUSA
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.
