commit ad91619aa9d78ab1c6d4a969c3db68bc331ae76c upstream

The INAND_CMD38_ARG_EXT_CSD is a vendor specific EXT_CSD register, which is
used to prepare an erase/trim operation. However, it doesn't make sense to
use a timeout of 10 minutes while updating the register, which becomes the
case when the timeout_ms argument for mmc_switch() is set to zero.

Instead, let's use the generic_cmd6_time, as that seems like a reasonable
timeout to use for these cases.
