regulator: qpnp-labibb-regulator: Restart LAB/IBB after SC fault

PBS will be triggered in PMIC hardware to disable LAB/IBB regulators
when a SC(short circuit) error is happened. The regulators won't be
restart in hardware and they will be kept disabled always after that.
Restart LAB/IBB regulator in the software if SC IRQ is detected, but
stop doing this if the SC IRQ had fired frequently.
