platform/x86: mlx-platform: Add support for new system type

Browse source 
Add support for new Mellanox system types of basic class VMOD0009,
containing Mellanox systems equipped with the switch devices
Spectrum 1 (32x100GbE Ethernet switch) and Switch-IB/Switch-IB2
(36x100Gbe InfiniBand switch).
These are the Top of the Rack system, equipped with Mellanox Comex
card.
