platform/x86: mlx-platform: Add support for new 200G IB and Ethernet systems
It adds support for new Mellanox system types of basic classes qmb7, sn34, sn37, containing systems QMB700 (40x200GbE InfiniBand switch), SN3700 (32x200GbE and 16x400GbE Ethernet switch) and SN3410 (6x400GbE plus 48x50GbE Ethernet switch). These are the Top of the Rack systems, equipped with Mellanox COM-Express carrier board and switch board with Mellanox Quantum device, which supports InfiniBand switching with 40X200G ports and line rate of up to HDR speed or with Mellanox Spectrum-2 device, which supports Ethernet switching with 32X200G ports line rate of up to HDR speed.
