[PATCH 1/2] ARM: dts: sun8i: h2+: Fix Orange Pi Zero device description.

From: Michal Suchanek
Date: Thu Oct 08 2020 - 14:40:14 EST

There are two models of Orange Pi zero which are confusingly marketed
under the same name. Old model comes without a flash memory and current
model does have a flash memory. Build device tree for each model.
