clk: sunxi-ng: sun6i-rtc: split main oscillator div and gate

Browse source

On the a733 the "osc24M-32k" clock has the same gate bits as the previously
supported SoC but a different divider implementation.

Instead of a fixed 750 divider, the divider is selected based on the
rate of the oscillator. It can be seen as a simple read-only divider.

On the A733 the gate and the divider are on different register which is
not supported by sunxi combined clocks. These element will be split on the
A733. Split them for the older SoC as well to keep on sharing the gate
definition.
