iio:ABI docs: Fix issue around repeated definition of out_currentY_raw
This one is challenging as both the places this appears in specific drivers are making 'unusual' uses of what looks like a simple output current channel. As a side note, this was particular bit of ABI occurs in other drivers where the use is much more straight forward e.g. dac/ad5421 This patch attempts to make a best effort of adding it to the main docs but retaining enough information. Both of these drivers probably need specific documents being written to describe their unusual interfaces, but those should be in the main documentation, not under Documentation/ABI. That is a non trivial job so left for another time.
