…SIC_PWR_OFF (#25589)

#### Why I did it
For NH-5010, ASIC_PWR_OFF feature is missing from the DPM configuration. This means ASIC is not power cycled as part of asic_init.sh, which is incorrect.

The failure looks like asic_init failure when system recovers from kernel panic (which does not power cycle the whole system), and is DUT-dependent. We can consistently reproduce on humm109 DUT only.

##### Work item tracking
- Microsoft ADO **(number only)**:

#### How I did it
Swap to use FPGA bit for DP_PWR_ON_DRV instead of ASIC_PWR_OFF.

#### How to verify it

On any DUT:
- Apply asic_init.sh changes
- Run reboot / test_reload_config / test_memory_exhaustion tests in sonic-mgmt, or manually confirm `show system-health summary` is good after reboot / config reload / kernel panic asic init scenarios.

On humm109 DUT:
- Apply asic_init.sh changes
- Run reboot / test_reload_config / test_memory_exhaustion tests in sonic-mgmt, or manually confirm `show system-health summary` is good after reboot / config reload / kernel panic asic init scenarios.

#### Why I did it

As per the requirements, adjusted the buffer settings for NH5010 hwSKUs.

##### Work item tracking
- Microsoft ADO **(number only)**:

#### How I did it

Modified the corresponding buffer_defaults_t2.j2, qos.json.j2 and pg_profile_lookup.ini files.

#### How to verify it
Verified the latest settings on sonic-mgmt QOS/PFCWD tests on NH5010 HWSKU.

If PR needs to be backported, then the PR must be tested against the base branch and the earliest backport release branch and provide tested image version on these two branches. For example, if the PR is requested for master, 202211 and 202012, then the requester needs to provide test results on master and 202012.
