platform/x86: mlx-platform: Add support for new msn201x system type
It adds support for new Mellanox system types of basic half unit size
class msn201x, containing system MSN2010 (18x10GbE plus 4x4x25GbE) half
and its derivatives. This is the Top of the Rack system, equipped with
Mellanox Small Form Factor carrier board and switch board with Mellanox
Spectrum device, which supports Ethernet switching with 32X100G ports line
rate of up to EDR speed.
