Subject: [PATCH v3 3/4] arm64: dts: qcom: Add PURWA-IOT-SOM platform

From: Yijie Yang <yijie.yang@....qualcomm.com>

The PURWA-IOT-SOM is a compact computing module that integrates a System
on Chip (SoC) — specifically the x1p42100 — along with essential
components optimized for IoT applications. It is designed to be mounted on
carrier boards, enabling the development of complete embedded systems.

Make the following peripherals on the SOM enabled:
- Regulators on the SOM
- Reserved memory regions
- PCIe3, PCIe4, PCIe5, PCIe6a
- USB0 through USB6 and their PHYs
- ADSP, CDSP
- Graphic
