platform/x86: mlx-platform: Extend FAN and LED configuration to support new MQM97xx systems

Add support for new system types "MQM97xx", which is based on Mellanox
Quantum-2 ASIC. It provides up to 64x400GB/s (IB) full bidirectional
bandwidth per port using PAM-4 modulation. The system support 32 OSFP
cages that can provide 64x400GB/s per port (two ports/cage). The system
fits standard 1U racks.

System is equipped with seven fan drawers and with per fan drawer LED
on backport panel and uses two-bytes for exposing CPLD Part Number
versions.

System is recognized by "DMI_BOARD_NAME" match, when this field is set
to "VMOD0010".
