A quirk proposed by Anton fixes the issue.  The attached patch adds the
quirk for the Marvell CAFE controller.



Subject: [PATCH] SDHCI: Add NO_BUSY_IRQ quirk for Marvell CAFE host chip

As described here: http://lkml.org/lkml/2009/2/20/265

The CAFE chip is broken due to commit e809517f6fa5803a5a1cd56026f0e2190fc13d5c.
Anton added a quirk here: http://lkml.org/lkml/2009/2/20/279 that fixes
CAFE's problem.  This adds the quirk for CAFE.

Obviously, this depends upon Anton's patch.
