iio: kx022a: document new chip_info structure members

The kx022a driver supports a few different HW variants. A chip-info
structure is used to describe sensor specific details. Support for
sensors with different measurement g-ranges was added recently,
introducing sensor specific scale arrays.

The members of the chip-info structure have been documented using
kerneldoc. The newly added members omitted the documentation. It is nice
to have all the entries documented for the sake of the consistency.
Furthermore, the scale table format may not be self explatonary, nor how
the amount of scales is informed.

Add documentation to scale table entries to maintain consistency and to
make it more obvious how the scales should be represented.
