New platforms:
 
 - NVIDIA MSX4 BMC
 
   The NVIDIA MSX4 HPM (host platform module) is a reference board for
   managing up to 8 PCIe connected NVIDIA GPUs via ConnectX-8 (CX8)
   SuperNICs. The BMC manages all GPUs and CX8s for both telemetry and
   firmware update via MCTP over USB. The host CPUs are dual socket Intel
   Granite Rapids processors.

 Updated platforms:
 
 - ast2600-evb (ASPEED): Various tidy-ups to address binding warnings
 - bletchley (Meta): Watchdog fix, tidy-ups to address binding warnings
 - clemente (Meta): HDD LED fix, GPIO line names, EEPROMs
 - harma (Meta): fanboard presence GPIO
 - santabarbara (Meta): IPMB, GPIO line names, additional IO expander
