Can't the mtd-mac-address be moved to the ar9342_ubnt_xw.dtsi? Don't we 
need pll-data here?

I guess it is related to the issues in "[PATCH 2/5] ath79: 
ubnt-bullet-m-xw: Move common DTS bits into XW include file".

I can not find an ar71xx board which uses "nano-m-xw" as userspace 
boardname. What's the purpose of adding the string to the supported devices?
