Kebo Liu e286869b24
[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 1/5] platform: mellanox: Introduce support of
new Nvidia L1 switch
Add support for new L1 switch nodes providing L1 connectivity for
multi-node networking chassis.
The purpose is to provide compute server with full management and IO
subsystems with connections to L1 switches.
System contains the following components:
- COMe module based on Intel Coffee Lake CPU
- Switch baseboard with two ASICs, while
24 ports of each ASICs are connected to one backplane connector
32 ports of each ASIC are connected to 8 OSFPs
- Integrated 60mm dual-rotor FANs inside L1 node (N+2 redundancy)
- Support 48V or 54V DC input from the external power server.
Add the structures related to the new systems to allow proper activation
of the all required platform driver.
Add poweroff callback to support deep power cycle flow, which should
include special actions against CPLD device for performing graceful
operation.
