[PATCH platform-next 3/3] platform/x86: mlx-platform: Add support for new system SGN2410

[Vadim Pasternak <vadimp@nvidia.com>]

Add support for new system type, which is a water-cooling flavor
of the VMOD001 system class, equipped with 48xSFP28 and 8xQSFP28
100G Ethernet ports.

System is recognized by "DMI_BOARD_NAME" and " DMI_PRODUCT_SKU"
matches, when these fields are set respectively to "VMOD001" and
"HI138".
