MicroSD card Driver of IMX6ULL

Hi Guys,

Playing the bare metal SD/MMC driver. 

Tried the examples under driver_examples\sdcard and driver_examples\mmccard.

Failed at the init(). 

Guess the IOMUX setting ups wrong. Updated #define BOARD_USDHC_MMCCARD_POWER_CONTROL(state) \

    BOARD_USDHC_SDCARD_POWER_CONTROL(state) in board.h file
Anybody has any idea/examples? Thanks a lot! 
Cheers,
Jesse
