Subject: [PATCH v3] arm64: dts: qcom: sc8280xp: Introduce additional tsens
instances
The SC8280XP contains two additional tsens instances, providing among
other things thermal measurements for the GPU.
Add these and a GPU thermal-zone.

Changes in v3:
- Sorted tsens nodes by address.
- Link to v2: https://lore.kernel.org/r/20240126-sc8280xp-tsens2_3-v2-1-8504d18828de@quicinc.com
Changes in v2:
- Drop TM/SROT comments
- Remove polling delays, rely on interrupts
- Link to v1: https://lore.kernel.org/r/20240118-sc8280xp-tsens2_3-v1-1-e86bce14f6bf@quicinc.com
