[Mellanox] Update HW-MGMT package to new version V.7.0030.1011 (#16239)
- Why I did it
1. Update Mellanox HW-MGMT package to newer version V.7.0030.1011
2. Replace the SONiC PMON Thermal control algorithm with the one inside the HW-MGMT package on all Nvidia platforms
3. Support Spectrum-4 systems

- How I did it
1. Update the HW-MGMT package version number and submodule pointer
2. Remove the thermal control algorithm implementation from Mellanox platform API
3. Revise the patch to HW-MGMT package which will disable HW-MGMT from running on SIMX
4. Update the downstream kernel patch list

Subject: [PATCH backport v.5.10 1/1] platform: mellanox: mlx-platform: Modify
graceful shutdown callback and power down mask
Use kernel_power_off() instead of kernel_halt() to pass through
machine_power_off() -> pm_power_off(), otherwise axillary power does
not go off.
Change "power down" bitmask.
