clk: sunxi-ng: mux: Increase fixed pre-divider div size

Some clocks have a predivider value that is larger than what u8 can store. One such example is the OUT clk found on A20/A31, which has a /750 pre-divider on one of the osc24M parents. Increase the size of the div field to u16. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
