The commit: d9dbb97be0e4a550457aec5f11afefb446169c90
"mmc: dw_mmc: Zap endless timeout" removed endless loop waiting for end
of dw mmc transfer.
For some workloads - dfu test @ Odroid XU3 (sending 8MiB file) -
and SD cards (e.g. MicroSD Kingston 4GiB, Adata 4GiB)
the default timeout is to short.
The new value - 20 seconds - takes into account the situation when SD card
triggers internal clean up. Such process may take more than 10 seconds on
some cards.
