[PATCH 2/4] clk: sunxi-ng: multiplier: Fix fractional mode

[Jernej Skrabec <jernej.skrabec@siol.net>]

Driver for multiplier clock is missing a call to
ccu_frac_helper_enable() when fractional mode is selected.

Add a call to ccu_frac_helper_enable().

Fixes: d77e8135b340 ("clk: sunxi-ng: multiplier: Add fractional support")
