This adds an initial dts for the Dragonboard 845. Supported functionality includes Debug UART, UFS, USB-C (peripheral), USB-A (host), Ethernet, microSD-card and Bluetooth. Initializing the SMMU is clearing the mapping used for the splash screen framebuffer, which causes the baord to reboot. This can be worked around using: fastboot oem select-display-panel none Ethernet and the second USB-A port depends on a functional firmware loader for the uPD720201.
