Add linux device tree entry related to the Meta (Facebook) compute node
system using an AST2600 BMC.
This node is named "Santabarbara". It is a compute node with accelerator
module. The system monitors voltage and temperature for the CPU, switch,
and NIC components on the motherboard and switch board.
