* Remove micro-DTSI mt7621_dlink_dir-882-x1.dtsi to ease reading
config without too much inheritance
* Use "separate" partitioning DTSIs so we can use the partitioning
without a complete match on the other settings (i.e. without the
former parent DTSI)
* Rename files to express the new organization
