[PATCH v2] clk: exynos4: Add PPMU IP block source clocks.

From: Jonghwa Lee
Date: Tue May 27 2014 - 07:27:21 EST

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_PPMUCAMIF, CLK_PPMUTV, CLK_PPMUMFC_L,
CLK_PPMUMFC_R, CLK_G3D, CLK_PPMUIMAGE, CLK_PPMULCD0, CLK_PPMULCD1,
CLK_PPMUFILE, CLK_PPMUGPS, CLK_PPMUDMC0, CLK_PPMUDMC1, CLK_PPMUCPU,
CLK_PPMUACP,
