[RESEND PATCH v2 3/3] iio: documentation: light: Add veml6030 sysfs documentation

[Rishi Gupta]

The driver for veml6030 light sensor provides custom sysfs entries
used to know parameters supported by the driver and to configure
sensor like setting power saving mode and persistence etc. This
commit document them.
