[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 5.10 2/5] platform: mellanox: Split initialization
procedure
Split mlxplat_init() into two by adding mlxplat_pre_init().
Motivation is to prepare 'mlx-platform' driver to support systems
equipped PCIe based programming logic device.
Such systems are supposed to use different system resources, thus this
commit separates resources allocation related code.
