This commit adds basic DT support for the Orion5x SoC family. It adds an orion5x.dtsi description of the Orion5x SoC as well as the needed DT_MACHINE structure to support boards converted to DT in the future. So far, the Device Tree contains the interrupt controller, the GPIO bank, the UART controllers, the SPI controller, the watchdog, the SATA controller, the I2C controller and the cryptographic engine.
