iio: light: veml6030: drop processed info for white channel

The resolution of the WHITE channel is not provided by the manufacturer,
neither in the datasheet nor in the application note (even their
proprietary application only processes the ALS channel, giving raw
values for WHITE).

The current implementation assumes that both resolutions are identical,
which is extremely unlikely, especially for photodiodes with different
spectral responses.

Drop the processed information as it is meaningless.
