There are 2 versions of the SoC. MT7623N is almost identical to MT7623A but has some additional multimedia features. The reference boards are available as NAND or MMC and might have a different ethernet setup. In order to reduce the duplication of devicetree code we add an intermediate dtsi file for these reference boards. Additionally MTK/WCN pointed out, that the EVB is yet another board and the board in question is infact the RFB. Take this into account while renaming the files.
