Subject: [PATCH] Revert "iio: add modifiers for A and B ultraviolet light"

This reverts
b89710bd215e ("iio: add modifiers for A and B ultraviolet light")

Enum iio_modifer is *ABI*, you can't just decide to change all the
values from one version to another, otherwise you break userspace.
The new entries should have been added to the end of the enum.
