The VEML6075 requires a single supply to operate. The property already
exists in the bindings and it is used in the example, but it is still
not on the list of required properties.
Signed-off-by: Javier Carrasco <[email protected]>

The driver and bindings for the VEML6075 UV sensor were merged in the
merge window for v6.8 i.e. they have not been released yet beyond rc.
Applying this patch as a fix now would avoid an ABI break like the
recently discussed here:
https://lore.kernel.org/linux-iio/[email protected]/
On the other hand, from the same discussion it can be concluded that the
major risk would be a potential warning with dtbs_check, in case this
patch is applied during the next merge window.
The VEML6075 driver already handles the power supply with
devm_regulator_get_enable().

I don't care if it introduces a dtbs_check problem, we can fix those.
The device clearly needs power and at least for linux it being missing
gets handled perfectly fine. I think it's pretty reasonable to do this.

Applied to the togreg branch of iio.git and pushed out as testing.
