[PATCH v3 2/8] clk: sunxi-ng: div: Add kerneldoc for the _ccu_div structure

[Maxime Ripard <maxime.ripard@free-electrons.com>]

The internal _ccu_div structure is meant to be embedded into other
structures to combine the various dividers and to form the clock classes
support.

Start to document those structures by using kerneldoc.
