MZK-DP150N、新リビジョンで起動可能に

MZK-DP150N、新しいリビジョン(おそらくは2017頃からのモデル)ではOpenWrtでFlashが認識できない問題が発生していましたが、パッチが入ったので起動できる様になりました。
注意：snapshotビルドのみ対応されています。
r7020-43d70a7で当方動作確認済み。

該当する修正はこちら。
kernel: Add support spi-nor, Eon EN25QH32
ramipsは既に4.14に移行しているが、他のカーネルバージョンにも適応される様にしてあるので、他の機種で同じチップが使われている場合にも救える筈。
同様の問題は聞いていないので該当機種が存在するかは不明。


Eon EN25QH32の対応自体は、linux-mtdに入るので、OpenWrtに関わらず対応する形になる。
mtd: spi-nor: Add support for EN25QH32
データシートは、以下から入手可能。(EONはESMTに買収されているのもあり、EONのサイトからダウンロードできなくなってる。。。)
