This change is to adapt to shift of ACR t234 safety code from
iGPU to dGPU.
Required changes consists of:
Adding support for new LSB, WPR and ACR descriptor structures
which are more aligned with what dGPU currently uses.
Change old riscv LSB header to version 1, as version 2 will
be used for new header to align with dGPU header nomenclature.

On T234 theCTXSW LS ucodes are encrypted. ACR will perform the
decryption and the decrypted content will be written back
into the same WPR location. So on recovery with LSPMU absence
and on warm boot case, to perform the authentication , the ucode
blob needs to be copied into the WPR from sysmem always.
Below are the LS ucodes authentication type
* LSPMU - Only Signed ( Only for non-safety build, for safety LSPMU is NA)
* CTXSW FECS/GPCCS - Encrypted and Signed (on both safety and non-safety build)

Some of the functions with no traceability to unit tests are already
covered by callee API functions. Skip these functions in SWVR by
skipping doxygen for them.
Some of the functions are non-fusa like those in profile.h and
bsearch.h. Those were included as the header was included in
Doxygen sources. Mark then non-safe.
Some of the nvgpu functions were not added to Targets entries for
respective tests. Fix those.

The emulate mode support is determined after chip detect and is flagged
by using NVGPU_SUPPORT_EMULATE_MODE flag. The present logic prevents
user from configuring the emulate mode sysfs knobs if this flag is not
set, however the emulate mode usecase requires the user to configure the
syfs knob prior to power-on, hence defer emulate mode check to a later
stage after chip detect.

Most of the Orin chip specific code is compiled out of safety build
with CONFIG_NVGPU_NON_FUSA and CONFIG_NVGPU_HAL_NON_FUSA. Remove the
config protection from Orin/GA10B specific code. Currently all code
is enabled. Code not required in safety will be compiled out later
in separate activity.
Other noteworthy changes in this patch related to safety build:
- In ga10b_ce_request_idle(), add a log print to dump num_pce so that
compiler does not complain about unused variable num_pce.
- In ga10b_fifo_ctxsw_timeout_isr(), protect variables active_eng_id and
recover under CONFIG_NVGPU_KERNEL_MODE_SUBMIT to fix compilation
errors of unused variables.
- Compile out HAL gops.pbdma.force_ce_split() from safety since this HAL
is GA100 specific and not required for GA10B.
- Compile out gr_ga100_process_context_buffer_priv_segment() with
CONFIG_NVGPU_DEBUGGER.
- Compile out VAB support with CONFIG_NVGPU_HAL_NON_FUSA.
- In ga10b_gr_intr_handle_sw_method(), protect left_shift_by_2 variable
with appropriate configs to fix unused variable compilation error.
- In ga10b_intr_isr_stall_host2soc_3(), compile ELPG function calls
with CONFIG_NVGPU_POWER_PG.
- In ga10b_pmu_handle_swgen1_irq(), move whole function body under
CONFIG_NVGPU_FALCON_DEBUG to fix unused variable compilation errors.
- Add below TU104 specific files in safety build since some of the code
in those files is required for GA10B. Unnecessary code will be
compiled out later on.
hal/gr/init/gr_init_tu104.c
hal/class/class_tu104.c
hal/mc/mc_tu104.c
hal/fifo/usermode_tu104.c
hal/gr/falcon/gr_falcon_tu104.c
- Compile out GA10B specific debugger/profiler related files from
safety build.
- Disable CONFIG_NVGPU_FALCON_DEBUG from safety debug build temporarily
to work around compilation errors seen with keeping this config
enabled. Config will be re-enabled in safety debug build later.

data structures used while requesting firmwares - sec2_fw, sec2_desc

The lsfm_free_nonpmu_ucode_img_res() API only frees the 'data' field
of struct nvgpu_firmware, but not the entire struct.
Fix these memory leaks by calling nvgpu_release_firmware() API

* As of now, working on multiple chip bringup in nvgpu-next repo has
an issue because we end with losing control on source code (hard to
find which part of the code belongs to which chip) and it's valuable
history this affects chip migration on release.
* To support multiple chip bringup simultaneously, we need new
guidelines to avoid losing control on source code and make migration
easier. This change adds links to nvgpu-next repo.
* Updated return code to ENODEV for consistency
* Updated ACR unittest to work with ENODEV return code
NOTE:
These are the initial set of infrastructure changes, guidelines
will evolve, and source code will get updated accordingly.
Based on future chip features, Which part of the source code falls
under nvgpu-next repo is decided.
