Cover letter [PATCH v3 0/3] fsi: sbefifo: Prevent async FFDC collection for Odyssey SBEFIFOs

A new type of SBE, found on the Odyssey chip, will return any async FFDC in the next transaction, so collecting the FFDC is unnecessary and results in unexpected behavior. This difference in behavior between the Odyssey SBE and the POWER9/10 SBEs wasn't apparent when support for the Odyssey was added. To fix the unexpected behavior, turn off the async collection fot Odyssey SBEFIFOs.

Changes since v2:
- Update commit messages slightly
- Rename dts binding file
- Remove '|' after description in dts binding
- Change generic node name in dts binding to match fsi.txt

Changes since v1:
- Change "ody" to "odyssey"
- Fix minor issues in binding document
