Working eSPI for IPCC UART packets using oob message mechanism

[nathanaelhuffman]

New FPGA, with FPGA-internal changes only to support IPCC over eSPI. No interface or register map changes, boots fine on ruby with grapefruit!

I know grapefruit is fast and loose, but I think there is value in pointing to where the collateral comes from (example). Otherwise right now we don't really know the origin. At very least we should have the Quartz commit somewhere. Ideally it would be a commit off main, but I'm not going to die on that hill for a dev system.

Thanks!

Fixed with a link to the commit on quartz main, image was built off that commit by ci.
