Changes in v3:
- Correct power monitor shunt resistor
- Revert the previous SGPIO P0_I3C_APML_ALERT_L renaming change
- Add new SGPIO line names and rename signal
- Retitle Update sensor configuration for more clarity
- Link to v2: https://lore.kernel.org/r/20251120-yv5_revise_dts-v2-0-4d7de701c5be@gmail.com

Changes in v2:
