Done in v2.  The whitespace got lost when pasting from a wrapped
editor - v2 uses tabs and the same indent as the surrounding
blocks.

Done in v2.  The separate _scale stanza is gone; the shared
_scale block at the top of the file now has one extra line:

  IIO_VOLUMEFLOW    litres per second

The _raw block stays for the per-channel-type description and
points at the shared _scale section for the units.
