clk: sunxi: Add support for table-based divider clocks
A few of the clock modules have odd dividers, such as
the 2 lowest dividers being the same (2), or have the
same divider when the highest bit is set.
This patch adds support for optional divider tables,
so the clock framework will know about the odd values.
