dt-bindings: clock: samsung: remove define with number of clocks

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.
Remove it entirely from the bindings, once Linux drivers stopped using
them.

clk: samsung: Add dt bindings for Exynos4412 ISP clock controller

Some registers for the Exynos 4412 ISP (Camera subsystem) clocks are
located in the ISP power domain. Because those registers are also
located in a different memory region than the main clock controller,
support for them can be provided by a separate clock controller.

clk: samsung: exynos4: Use single clock ID for CLK_MDMA gate clocks

Exynos4210 and Exynos4x12 SoCs have the PL330 MDMA IP block clock
defined exactly in same way in documentation. Using different
names for these clocks is a bit misleading. Since there is no users
of CLK_MDMA2 in existing dts files this patch drops CLK_MDMA2 and
replaces it with CLK_MDMA in the driver. This ensures PL330 MDMA
has correct clock assigned on Exynos4x12 SoCs.
