power: smb5: Add moisture detection support for pmi632

Presence of moisture expedites the corrosion of Type-C/uUSB ID pins
due to constant DRP toggling. To reduce the effect of corrosion,
set DRP toggling duty cycle to 1% and suspend usb input on water
detection.

Use property MOISTURE_DETECTED to reflect moisture detection status.
