power: qpnp-fg-gen4: Enable side loading of current during SOC re-estimate 



As per the hardware recommendation, clear the first logged main
current ADC values, enable side loading of current and voltage
before SOC re-estimate during battery profile loading. Clear the
side loading after SOC re-estimate is done.
