Subject: [PATCH 2/2] arm64: allwinner: a64: add device tree for SOPINE on Pine64 Clusterboard

The Pine64 SOPINE Clusterboard is a mini-ITX sized board capable
of hosting up-to 7 SOPINE modules. It is largely compatible
with the SOPINE baseboard but it omits most of the in- and
output interfaces. Also The Clusterboard needs a tx delay
of 500ps for ethernet to work.

Add a device tree for SOPINE on the Pine64 Clusterboard.
