Initial introduction of Facebook TioagaPass family equipped with
Aspeed 2500 BMC SoC. Neptune is a x86 server development kit
with a ASPEED ast2500 BMC manufactured by Facebook.
Specifically, This adds the tiogapass platform device tree file
including the flash layout used by the tiogapass BMC machines.
This also adds an entry of tiogapass device tree file in Makefile
as well an entry of Facebook in Documentation for vendor prefix
