regulator: hi6421: add supplier featuretracking-hilt-regulator-1113
Example: ldo0 supplies ldo1
dts:
ldo1: ldo@21 {
ldo-supply = <&ldo0>;
};
If supplier is register first, regulator is register successfully with supplier
If suplier is register late, regulator probe will be defered automatically,
while driver using such regulator may handle accordingly
Or change the supplier regulator sequence in dts
