qpnp-smb2: update AICL rerun logic for PM660 



Current AICL re-run design for PM660 uses AICL restart mechanism
which starts AICL algorithm from Min ICL value to the configure ICL
value one step (25mA) at a time, this adds considerable amount of
delay for algorithm to reach a settled ICL value. Fix this by using
PMI8998 based AICL re-run design.
