power: qpnp-smb5: Use the RECHARGE_SOC psy property to force recharge

In some cases PMI632 is unable to recharge when SOC drops below
the recharge-SOC threshold. In such a case, force a recharge
using the RECHARGE_SOC property which disables and re-enables
battery charging.

While at it, add the BATTERY_CHARGING property to allow users to
enable/disable battery charging.
