Possible bug fix in the MMC/SD driver.

In the a10_mmc_reset_controller function, the purpose of the do while loop is
to wait till the register reset is done or time out has occurred. 

In the current code, the do while loop will continue to loop if the reset is
done but timeout is not done. Also, it will exit if the reset is not done
instead of waiting for the time out to occur. The patch corrects this. 

In the a10_mmc_attach function, the maximum value of operable frequency is
termed as 50Hz, but it is coded as 52MHz which I have changed.
