arm64: dts: qcom: Add Dragonboard 845c 



This adds an initial dts for the Dragonboard 845. Supported
functionality includes Debug UART, UFS, USB-C (peripheral), USB-A
(host), microSD-card and Bluetooth.

Initializing the SMMU is clearing the mapping used for the splash screen
framebuffer, which causes the board to reboot. This can be worked around
using:
