staging: iio: light: isl29018: Remove non-standard sysfs attributes
This patch removes non-standard sysfs attributes range, range_available,
adc_resolution and adc_resolution_available. It also removes the
corresponding show and store functions.
This is in preparation for using standard IIO attributes in order to move
the code out of staging.
