arm64: dts: qcom: add SA8540P ride(Qdrive-3)

Introduce the Qualcomm SA8540P ride automotive platform, also known as
Qdrive-3 development board.

This initial contribution supports SMP, CPUFreq, cluster idle, UFS, RPMh
regulators, debug UART, PMICs, remoteprocs and USB.

The SA8540P ride contains four PM8450 PMICs. A separate DTSI file has
been created for PMIC, so that it can be used for future SA8540P based
boards.
