clk: sunxi-ng: Support multiple variable pre-dividers
On the A83T, the AHB1 clock has a shared pre-divider on the two
PLL-PERIPH clock parents. To support such instances of shared
pre-dividers, this patch extends the mux clock type to support
multiple variable pre-dividers.
As the pre-dividers are only used to calculate the rate, but
do not participate in the factorization process, this is fairly
straightforward.
