Subject: [PATCH 01/11] clk: samsung: exynos3250: 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 this number of clocks
should not be in the bindings, because otherwise we should not change
it.

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