This adds the devices tree for a new variant of the IOT2050 which comes
with two M.2 slots and is otherwise almost equivalent to the existing
Advanced PG2 variant (USB3 is available via M.2 now).

Furthermore, the device tree of the whole device series is extended to
also hold the QSPI layout.

Changes in v2:
 - alphabetic ordering in binding schema and makefile
 - dropped an unneeded blank line in patch 3
