Module acktimer

The SDMMC_ACKTIMER register contains the acknowledgment timeout period, in SDMMC_CK bus clock periods. A counter loads the value from the SDMMC_ACKTIMER register, and starts decrementing when the data path state machine (DPSM) enters the Wait_Ack state. If the timer reaches 0 while the DPSM is in this states, the acknowledgment timeout status flag is set.
