mmc: card: set timeout value for sanitize operation
mmc: card: set timeout value for sanitize operation

During secure discard, the sanitize operation is started
without any timeout value set, which result in a timeout
of 10 seconds applied at the SDHCi driver.

But since the sanitize operation was started after secure
discard was issued, it could take longer than 10 seconds.
So setting a timeout of 30 seconds based on testing done
so far.
