[PATCH 12/13] ARM: dts: imx: add i.MXRT1050-EVK support

[Jesse Taube <mr.bossman075@xxxxxxxxx>]

From: Giulio Benetti <giulio.benetti@xxxxxxxxxxxxxxxxxxxxxx>

The NXP i.MXRT1050 Evaluation Kit (EVK) provides a platform for rapid
evaluation of the i.MXRT, which features NXP's implementation of the Arm
Cortex-M7 core.

The EVK provides 32 MB SDRAM, 64 MB Quad SPI flash, Micro SD card socket,
USB 2.0 OTG.

This patch aims to support the preliminary booting up features
as follows:
GPIO
LPUART
SD/MMC
