[PATCH AUTOSEL 4.19 010/219] ARM: dts: imx31: Fix memory node duplication

From: Fabio Estevam <festevam@gmail.com>

[ Upstream commit 013d37e4707e24c7b9bc3fc55aeda55ce9c2b262 ]

Boards based on imx31 have duplicate memory nodes:

- One coming from the board dts file: memory@

- One coming from the imx31.dtsi file.

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