arm: dts: mediatek: add Genio 520/720 SNOR support
Add devicetree nodes needed to enable SNOR support on Genio 520 and 720
EVKs. This is copied from the most recent upstream submission [1] of the
devicetree for these boards, so there should be minimal differences when
we eventually switch to OF_UPSTREAM.
