SPI NOR flash was optional in the first production batch in Dec 2016.
In later batches flash chip was pre-populated. However there should
be quite a few boards around which do not have flash chip.
Add node for SPI NOR flash on orange-pi-zero board. Disable this node
by default and leave it to users to enable it if their board has
SPI NOR flash chip populated.
