[PATCH v9 3/5] regulators: axp20x: Use "clock-frequency" property for dcdc work frequency

Since the dcdc regulator work frequency is a property of the regulators
DT sub-tree, there is no issue of naming collisions, so we can use the
standard "clock-frequency" binding for this.
The driver sets a reasonable default value (same as the datasheet), and
only 1 dts has the old binding, with the default value.
