mci imx-esdhc: increase write timeout
The timeout for wating for the bus to be idle is too short when the card does internal garbage collection. This was triggered with filling an SD card under Linux with /dev/urandom, then doing a saveenv under barebox afterwards. Linux has timeouts here up to 300ms. Use a second to be safe.
