ramips: reorganize DTSI files for D-Link DIR-8xx

 * 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
