ARM: dts: imx7: Fix memory node duplication

Boards based on imx7 have duplicate memory nodes:

- One coming from the board dts file: memory@

- One coming from the imx7s.dtsi file.

Fix the duplication by removing the memory node from the dtsi file
and by adding 'device_type = "memory";' in the board dts.
