Whenever SDHC run at clock rate 50MHZ or below, the hardware data
timeout value will be 21.47secs, which is approx. 22secs and we have
a current software timeout value as 10secs. We have to set software
timeout value more than the hardware data timeout value to avioid seeing
the below register dumps.

So, set software timeout value more than hardware timeout value.
