power: qpnp-smbcharger: add low-volt-dcin device tree property 



Currently, we do AICL deglitch configuration dynamically for all
type of chargers whereas it should be applied specifically. As a
part of that, we need to differentiate low volt DCIN chargers.

Add a device tree property to support that requirement. If this
property is set, then AICL deglitch configuration will be applied
dynamically.
