[PATCH 4/4] arm64: dts: qcom: Add device tree for SA8797P Ride board

Shawn Guo

From: Deepti Jaggi <deepti.jaggi@oss.qualcomm.com>

Add initial device tree for the Qualcomm SA8797P Ride reference board.

- Configure UART15 as the primary console and UART4 as the secondary
serial port
- Enable UFS storage support
- Define thermal zones for PMIC dies, UFS, and two SDRAM sensors,
all sourced from SCMI sensor protocol on channel 23
