Subject: [PATCH RESEND v7 4/5] arm64: dts: freescale: add i.MX8DXL SoC support

i.MX8DXL is a device targeting the automotive and industrial market
segments. The chip is designed to achieve both high performance and
low power consumption. It has a dual (2x) Cortex-A35 processor.

This patch adds the basic support for i.MX8DXL SoC.
