platform: mellanox: Introduce support for rack manager switch
The rack switch is designed to provide high bandwidth, low latency connectivity using optical fiber as the primary interconnect. System supports 32 OSFP ports, non-blocking switching capacity of 25.6Tbps. System equipped with: - 2 replaceable power supplies (AC) with 1+1 redundancy model. - 7 replaceable fan drawers with 6+1 redundancy model. - 2 External Root of Trust or EROT (Glacier) devices for securing ASICs firmware.
