Subject: [PATCH] ARM: dts: imx6qdl-nitrogen6x: Add SPI NOR partitions

This adds the partitions definition for the SPI NOR to provide
backward compatibility with the documented[1] layout used with
Boundary Devices BSP.

1. https://boundarydevices.com/boot-flash-access-linux/

It exports to Linux:

mtd0: U-Boot
mtd1: U-Boot Environment
mtd2: Bootsplash
