I made a few attempts at splitting this up, mainly into two patches (one for moving MPIO code from vendorcode into driver, and another for moving/renaming chip ops and updating devicetrees). I end up having to add intermediary changes in each patch for them to make sense and build individually, which are then reverted anyway. If possible, I think it'd be more practical to have these changes within a single patch.
