[PATCH v4 2/2] arm64: dts: qcom: Add Advantech SOM-DB5830

[Yuanjie Yang <yuanjie.yang@oss.qualcomm.com>]

Add the initial device tree for the Advantech SOM-DB5830 platform based on
the Qualcomm X1E80100 SoC.

The platform consists of an Advantech SOM-6820 system-on-module (SoM)
mounted on an Advantech SOM-DB5830 carrier board. The SOM integrates an
IQ X7181 EVK SiP containing the Qualcomm X1E80100 SoC and its supporting
components.

Compared to the HAMOA IOT EVK, PCIe controllers 3, 5 and 6 are routed to
expansion slots, while PCIe controller 4 is connected to an ASM1164
SATA controller. The platform does not provide a USB Type-C connector.
The eUSB repeater (TUSB2E111YCGR) is configured through hardware strapping
pins and therefore requires no software control.

The initial device tree includes support for:
- UART
- Regulators
- USB
- PCIe
- Pinctrl
- ADSP, CDSP
- UFS
- Graphics
- Video

Regulators, pinctrl, graphics, video, ADSP and CDSP support are
inherited from the common hamoa-iot-som.dtsi description.
