SDMMC:

SDMMC:
1. When CMD_TIMEOUT or DTO_TIMEOUT occur again, directly stop card to be used, rather than to printe error log always.
   In the case, you will see log ( I am very sorry to tell you,in order to make the machine correctly,you must remove-insert card again.)

2.Increase processing not detect-pin for card in your project. then you have to define detect_irq as INVALID_GPIO in your board_xxxx.c
  because there is not detect-pin in some project.
