arm64: dts: qcom: shikra: Add PMIC thermal and ADC support
Add PMIC topic overlay changes for Shikra SOM variants (CQM, CQS, IQS): - Add pm4125 temp-alarm and VADC channel nodes - Add pm8005 temp-alarm node - Add thermal zones for PMIC and system thermistors - Add GPIO key (volume up) bindings - Add ADC thermal bridge nodes for pa/quiet/msm thermistors - Disable pm8005 regulators across SOM variants - Switch SPMI interrupt to MPM edge-triggered Signed-off-by: Rakesh Kota <rakesh.kota@oss.qualcomm.com>
