[PATCH 09/22] clk: sunxi: Implement A31 PLL6 as a divs clock for 2x output

2014-05-23T08:27:41Z

Some clock modules on the A31 use PLL6x2 as one of their inputs.
This patch changes the PLL6 implementation for A31 to a divs clock,
i.e. clock with multiple outputs that have different dividers.

This behavior is consistent with previous SoC's by Allwinner.
