iio: ABI: document calibscale_available attributes

Browse Source 
There are a number of light sensor drivers that have various
calibscale_available attributes. Up to now, these were missing from
the documentation.

Kernel version 4.8 is used since the first use appears to be in
commit eb869ade30 ("iio: Add tcs3472 color light sensor driver").
