mmc: increase SD write timeout for crappy cards
It seems that some cards are slightly out of spec and occasionally will not be able to complete a write in the alloted 250 ms [1]. Incease the timeout slightly to allow even these cards to function properly. [1] http://lkml.org/lkml/2008/9/23/390 Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
