soc: qcom: eud: pet hw when ldo24 is turned on or off

EUD is currently being pet in USB driver in charger call back
context when USB cable is connected or disconnected. This design is
not scalable for internal or external design which does not use
charger sw or hw.  Move petting logic to eud driver and pet the hw
depending on ldo24 status.
