From: Sean Wang <sean.wang@xxxxxxxxxxxx>
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 Mediatek 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.
