qpnp-smb2: support exiting sink based on cc

While PD is under hard reset and the device is in sink mode, it
shouldn't leave sink mode because VBUS goes away. Instead it should
stay in sink mode while hard reset is being conducted and exit sink
mode only if CC gets detached.

Configure the exit state when hard reset is in progress. Also while
hard reset is in progress disable APSD else a APSD could run and
disturb SDP communication after VBUS recovers in hard reset procedure.
