Subject: [PATCH 1/2] dw_mmc:  Run card detect tasklet during slot initialisation.

We need to run the card detect tasklet at the end of slot initialisation
as it is possible that a card has been inserted prior to boot, so we miss
the insertion interrupt and now the card is sitting there inserted but with
no power to it.
