Add initial devicetree support for the Vicharak Axon Lite, an RK3576-based single-board computer. Supported peripherals: - RK806 PMIC with CPU-big, CPU-little, GPU, NPU and logic regulators - Mali GPU - Gigabit Ethernet (RGMII, RTL8211F PHY) - eMMC (HS400, enhanced strobe) - microSD card slot (UHS-SDR104) - UFS storage - PCIe0 and PCIe1 - HYM8563 RTC - GPIO LEDs (status, heartbeat) - UART0 serial console Tested by booting to a userspace shell over the serial console and verifying eMMC, microSD, UFS storage, PCIe and Ethernet link-up.
