Peng Fan d0f8516d9e imx: mx7ulp: Add clock framework and functions 
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.
