[PATCH V5 1/2] dt-bindings: iio: light: isl29018: update power supply name

[Anson Huang]

According to datasheet, the isl29018 has "vddd/vdda" power
supply, the "vdda" and "vddd" MUST be shorted externally,
and isl29023/isl29035 ONLY has "vdd" power supply, so just
one regulator is needed for the driver, update the power
supply name with "vdd" according to datasheet to avoid
confusion.

ChangeLog since V4:
	Since ONLY isl29018 has two power supplies and they are MUST shorted externally, so they can be
	treated as one power supply as well, remove "vdda" power supply and ONLY update the "vcc" with
	"vdd" according to datasheet.
