power: qpnp-smbcharger: handle the removal of OCP 



Currently, we handle the removal of DCP/HVDCP in UV interrupt
handler and the removal of SDP/CDP in source detect interrupt
handler. For the cases of OCP (other charging port), we are
not handling the removal even though it might have got detected
in the source detection process. Add support to handle it.
