Initial support for Avnet MiniZed board. Tested UART1 (serial console), QSPI(Flash), SDHCI1 (eMMC), USB.

Signed-off-by: Ibai Erkiaga ibai.erkiaga-elorza@xilinx.com ---

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
