ARM: dts: imx7d: sbc-imx7: add basic board support

SBC-iMX7 is a single board computer designed for industrial
and embedded applications. It is based on the Freescale i.MX7
system-on-chip. SBC-iMX7 is implemented with the CL-SOM-iMX7
System-on-Module providing most of the functions, and SB-SOM-iMX7
carrier board providing additional peripheral functions and
connectors.
