Changes in v3:
        -dts formating refactor
        -CONFIG_DISPLAY_CPUINFO removed from config
        -CONFIG_OF_EMBED removed from config

Changes in v2:
        -board model changed to use Avent prefix
        -usb phy driver changed usb-no-xceiv
        -removed gpio and intc binding
        -fixed-partitions usage
