Samsung clock patches for v3.18

1) non-critical fixes (without the need to push to stable)

fa0111be clk: samsung: exynos4: remove duplicate div_core2 divider clock instantiation
b511593d clk: samsung: exynos4: fix g3d clocks
c1425430 clk: samsung: exynos4: add missing smmu_g2d clock and update comments
22842d24 clk: samsung: exynos5260: fix typo in clock name
e82ba578 clk: samsung: exynos3250: fix width field of mout_mmc0/1
59037b92 clk: samsung: exynos3250: fix width and shift of div_spi0_isp clock
5ce37f26 clk: samsung: exynos3250: fix mout_cam_blk parent list

2) Clock driver extensions

07ccf02b dt-bindings: clk: samsung: Document the DMC domain of Exynos3250 CMU
d0e73eaf ARM: dts: exynos3250: Add CMU node for DMC domain clocks
e3c3f19b clk: samsung: exynos3250: Register DMC clk provider
4676f0aa clk: samsung: exynos4: add support for MOUT_HDMI and MOUT_MIXER clocks
