Everything else looks okay though from a pinmux perspective.

Initial introduction of Portwell Neptune family equipped with Aspeed 2500 BMC SoC. Neptune is a x86 server development kit with a ASPEED ast2500 BMC manufactured by Portwell. Specifically, This adds the neptune platform device tree file including the flash layout used by the neptune machines.
