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: exynos3250: Register DMC clk provider

Add clock provider for clocks in DMC domain including EPLL and BPLL. The
DMC clocks are necessary for Exynos3 devfreq driver.

The DMC clock domain uses different address space (0x105C0000) than
standard clock domain (0x10030000 - 0x10050000). The difference is huge
enough to add new DT node for the clock provider, rather than extending
existing address space.

clk: samsung: exynos3250: Add clocks using common clock framework

This patch add new the clock drvier of Exynos3250 SoC based on Cortex-A7
using common clock framework. The CMU (Clock Management Unit) of Exynos3250
control PLLs(Phase Locked Loops) and generate system clocks for CPU, buses,
and function clocks for individual IPs.

The CMU of Exynos3250 includes following clock doamins:
- CPU block for Cortex-A7 MPCore processor
- LEFTBUS/RIGHTBUS block
- TOP block for G3D/MFC/LCD0/ISP/CAM/FSYS/MFC/PERIL/PERIR
