clk: samsung: exynos850: do not define number of clocks in bindings

Number of clocks supported by Linux drivers might vary - sometimes we
add new clocks, not exposed previously.  Therefore these numbers of
clocks should not be in the bindings, as that prevents changing them.

Define number of clocks per each clock controller inside the driver
directly.
