platform: mellanox: Introduce support for next-generation 800GB/s switch 

Introduce support for Nvidia next-generation 800GB/s ethernet switch
SN5600.

SN5600 is 51.2 Tbps Ethernet switch based on Nvidia Spectrum-4 ASIC.
It can provide up to 64x800Gb/s (ETH) full bidirectional bandwidth per
port using PAM-4 modulations. The system supports 64 Belly to Belly 2x4
OSFP cages.
The switch was designed to fit standard 2U racks.

Features:
- 64 OSFP ports support 800GbE - 10GbE speed.
- Additional 25GbE - 1GbE service port on the front panel.
- Air-cooled with 3 + 1 redundant fan units.
- 1 + 1 redundant 3000W or 3600W PSUs.
- System management board is based on Intel Coffee-lake CPU E-2276
  with secure-boot support.
