[PATCH V4 1/2] dt-bindings: iio: light: isl29018: update power supply name

[Anson Huang]

According to datasheet, the isl29018 has "vddd/vdda" power
supply, and isl29023/isl29035 ONLY has "vdd" power supply,
update the power supply name with "vdd" and "vdda" according
to datasheet to cover all devices and avoid confusion.
