Exynos4 has saveral PPMUs and each of them has operation clock which
can be gated through CMU's SFR control.
New clocks are listed below. All clocks are added as a gate-typed clock.
CLK_PPMULEFT, CLK_PPMURIGHT, CLK_PPMUG3D, CLK_PPMUCAMIF, CLK_PPMUTV,
CLK_PPMUMFC_L, CLK_PPMUMFC_R, CLK_PPMUIMAGE, CLK_PPMULCD0, CLK_PPMULCD1,
CLK_PPMUFILE, CLK_PPMUGPS, CLK_PPMUCPU, CLK_PPMUACP, CLK_PPMUDMC0,
CLK_PPMUDMC1
