Kevin Tung a5c59a2923 ARM: dts: aspeed: yosemite5: Add Meta Yosemite5 BMC 
Add device tree for the Meta (Facebook) Yosemite5 compute node,
based on the AST2600 BMC.

The Yosemite5 platform provides monitoring of voltages, power,
temperatures, and other critical parameters across the motherboard,
CXL board, E1.S expansion board, and NIC components. The BMC also
logs relevant events and performs appropriate system actions in
response to abnormal conditions.
