staging: iio: Documentation: Add missing sysfs docs for angle channel

Browse Source 
The iio resolver drivers in staging use angle channels. This patch
add missing documentation for this type of channel.

As was discussed in [1], radians is chosen as the unit, to match the
unit of angular velocity.
