Rajesh Devaraj 7dc013d242 gpu: nvgpu: merge error reporting apis
In DRIVE 6.0, NvGPU is allowed to report only 32-bit metadata to
Safety_Services. So, there is no need to have distinct APIs for
reporting errors from units like GR, MM, FIFO to SDL unit. All
these error reporting APIs will be replaced with a single API. To
meet this objective, this patch does the following changes:
- Replaces nvgpu_report_*_err with nvgpu_report_err_to_sdl.
- Removes the reporting of error messages.
- Replaces nvgpu_log() with nvgpu_err(), for error reporting.
- Removes error reporting to Safety_Services from nvgpu_report_*_err.

However, nvgpu_report_*_err APIs and their related files are not
removed. During the creation of nvgpu-mon, they will be moved under
nvgpu-rm, in debug builds.

Note:
- There will be a follow-up patch to fix error IDs.
- As discussed in https://nvbugs/3491596 (comment #12), the high
level expectation is to report only errors.
