arm64: dts: qcom: Add basic devicetree support for QRB5165 RB5

Add basic devicetree support for Qualcomm Technologies, Inc. Robotics
RB5 platform. This board is one of the 96Boards CE platform targeted for
Robotics usecases from Qualcomm.

This basic devicetree support includes regulators, onboard debug UART,
I2C, SPI, and UFS support.
