ARM: dts: Add support for dra718-evm
The DRA718-evm is a board based on TI's DRA718 processor targeting BOM-optimized entry infotainment systems and is a reduced pin and software compatible derivative of the DRA72 ES2.0 processor. This platform features: - 2GB of DDR3L - Dual 1Gbps Ethernet - HDMI, - uSD - 8GB eMMC - CAN - PCIe - USB3.0 - Video Input Port - LP873x PMIC More information can be found here[1]. Adding support for this board while reusing the data available in dra72-evm-common.dtsi.
