Add a clock framework to support SCG1/PCC2/PCC3 for A7 to support get/set clock source, divider, clock rate and parent source. Users need to include pcc.h to use the APIs to for peripherals clock. Each peripheral clock is defined in enum pcc_clk type. SCG relevants APIs are defined in scg.h which supports clock rate get, PLL/PFD enablement and settings, and all SCG clock initialization. User need use enum scg_clk to access each clock source. In clock.c, we initialize necessary clocks at u-boot s_init and implement the clock functions used by driver modules to operate clocks dynamically.
