power: qpnp-smb5: Add VBAT and SOC based recharge support

After termination, charging can be restarted based on the battery
voltage (VBAT) or SOC. Add support to enable recharge based on
VBAT and SOC. Both the recharge schemes are mutually
exclusive, when both are enabled SOC based recharge takes
precedence.
