Like the E3C246D4I, this is a reasonably affordable off-the-shelf
mini-ITX AST2500/Xeon motherboard with good potential as an OpenBMC
development platform.  Booting the host requires a modicum of eSPI
support that's not yet in the mainline kernel, but most other basic
BMC functionality is available with this device-tree.

Restructure GPIO table to fit maximum line length.

Fix mistakes found while working on OpenBMC userland configuration and
based on probing the board.

Schematic for this board is not available. Because of this the choice
was made to use a descriptive method for naming the GPIOs.

 - Push-pull outputs start with output-*
 - Open-drain outputs start with control-*
 - LED outputs start with led-*
 - Inputs start with input-*
 - Button inputs start with button-*
 - Active low signals end with *-n
