clk: sunxi-ng: Implement multiplier maximum
Some multipliers have a maximum rate that is lower than what the register width allows to. Add a field in the multiplier structure to allow CCU driver to set that maximum. Acked-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
