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.
