platform/x86: mlx-platform: Add support for new system XH3000

Add support for new system type XH3000, which is a water cooling
Ethernet switch blade equipped with 32x200G Ethernet ports.

The system is recognized by "DMI_BOARD_NAME" and "DMI_PRODUCT_SKU" matches,
when these fields are set to "VMOD0005" and "HI139" respectively.
