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.

This misses adding the devicetree to the dtb target in
arch/arm/boot/dts/aspeed/Makefile. Consequently I don't expect this was
tested with `make DTBS_CHECK=y ...`. Fixing the make target and
checking the DTB yields the following among the usual concerns:
arch/arm/boot/dts/aspeed/aspeed-bmc-facebook-yosemite5.dtb: ethernet@1e670000 (aspeed,ast2600-mac): Unevaluated properties are not allowed ('ncsi-package' was unexpected)
from schema $id: http://devicetree.org/schemas/net/faraday,ftgmac100.yaml#
Can you please address that? You may need to update or introduce a
binding document as part of doing so if it's not a matter of removing
the property from the devicetree.

Thanks for pointing out the mistake.
I have submitted v3 to add the missing devicetree to the DTB target
and to fix the error caused by unevaluated properties that are not
allowed.
