soc: qcom: pil: Add support for the CX IPeak mitigation
Clear the CX iPeak bit if it was set by MSS before crash.
MSS sets this bit if it was in Turbo state. In a situation
where all the votes were set (including MSS), It would have
resulted in CDSP throttling. But when MSS is in crashed state,
It cannot be cleared by MSS, So PIL needs to do this. It
would allow possible clearance of throttle state.
