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

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:

The current entry-latency-us is too short.
The proper way to convert between the device tree properties
from the vendor tree to the upstream PSCI device tree properties is:
entry-latency-us = qcom,time-overhead - qcom,latency-us
which gives
entry-latency-us = 210 - 80 = 130

This results in issues either to later start the CDSP, using the
