Device Tree bindings for max77819 Charger

Required Properties :
 - compatible : Should be "maxim,max77819-charger".

Optional Properties :
 - psy_name : Power supply name.
 - fast_charge_current : fast charge current(uA)
 - charge_termination_voltage : CV voltage(uV)
 - topoff_timer : topoff timer(min)
 - topoff_current : topoff current (uA)
 - charge_restart_threshold : restart charging threshold (uV)
 - enable_coop : enable dual charging with MAX8971.
		If you use only MAX77819 charger, you should not define it.

 - enable_thermistor : Enable thermistor
 - enable_aicl : enable AICL function.
 - aicl_detection_voltage : AICL detection voltage(uV)
 - aicl_reset_threshold : AICL reset threshold(uV)


Example:

		charger {
			compatible = "maxim,max77819-charger";
			psy_name = "max77819-charger";
			fast_charge_current = <0>;
			enable_thermistor;
			enable_aicl;
			aicl_detection_voltage = <4500000>;
			aicl_reset_threshold = <100000>;
		};
