ramips: mt7621: create DTSI for Xiaomi NAND devices
This creates a DTSI for Xiaomi devices with 128M NAND. This allows to consolidate the partitions and a few other nodes for AC2100 family and Mi Router 3G. Note that the Mi Router 3 Pro has 256M NAND and differently sized partitions. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de> Signed-off-by: maurerr <mariusd84@gmail.com>
