MLK-10176-3 imx: mx7: Add clock support
Since a new CCM with clock root slice is introduced in mx7. Provide several APIs for configuring root slice in clock_slice.c Implement clock/PLL relevant functions for modules in mx7d to enable/disable/set/get clocks or PLLs. From mx7d, the clocks are initialized in function "void clock_init(void)", such as UART, USDHC, ECSPI, USB, WDOG, WEIM. These module don't have clock setting functions in driver and BSP, and assume the clock is setup before entering into u-boot. Because default root clock is 24Mhz OSC, we have to setup these default clocks.
