[PATCH] clk: sunxi-ng: h6: Fix CEC clock

[Andre Przywara]

The CEC clock on the H6 SoC is a bit special, since it uses a fixed
pre-dividier for one source clock (the PLL), but conveys the other clock
(32K OSC) directly.
We are using a fixed predivider array for that, but fail to use the right
flag to actually activate that.
