Documentation: Add some notes about how to integrate FSP
While we don't _want_ FSP, we can't get around it sometimes. But when using it, we can still try to establish best practices to make life easier for everybody.

+## Integration Guidelines
+
+Some guiding principles when working on the glue to integrate FSP into
+coreboot, e.g. on how to configure a board in devicetree when that affects
+the way FSP works:
+
+* It should be possible to replace FSP based boot with a native coreboot
+ implementation for a given chipset without touching the mainboard code.
+* The devicetree configures coreboot and part of what coreboot does with the
+ information is setting some FSP UPDs. The devicetree isn't supposed to
+ directly configure FSP.
+
## Bugs
As Intel doesn't even list known bugs, they are collected here until
those are fixed. If possible a workaround is described here as well.
