Hi!

Update the bindings with the new properties used for
PMI8998.
Changes from V3:
    - Removed the default values.
Why?
+- qcom,current-limit-microamp
+	Usage:        optional
+	Value type:   <u32>
+	Definition:   uA; per-string current limit; value from 0 to 30000 with
+		      2500 uA step.
 
 - qcom,current-boost-limit
 	Usage:        optional
 	Value type:   <u32>
 	Definition:   mA; boost current limit.
 		      For pm8941: one of: 105, 385, 525, 805, 980, 1260, 1400,
-		      1680. Default: 805 mA
+		      1680.
 		      For pmi8998: one of: 105, 280, 450, 620, 970, 1150, 1300,
-		      1500. Default: 970 mA
+		      1500.
I'd say that optional properties should list default values...?
 - qcom,ovp
 	Usage:        optional
 	Value type:   <u32>
 	Definition:   V; Over-voltage protection limit; one of:
-		      27, 29, 32, 35. default: 29V
+		      27, 29, 32, 35.
 		      This property is supported only for PM8941.
Same here.
+- qcom,ovp-millivolt
+	Usage:        optional
+	Value type:   <u32>
+	Definition:   mV; Over-voltage protection limit;
+		      For pmi8998: one of 18100, 19600, 29600, 31100
+		      If this property is not specified for PM8941, it
+		      falls back to "qcom,ovp" property.
+
"voltage-limit-millivolt"? "ovp" is not really well known acronym.
