From: Christopher Spinrath <christopher.spinrath-vA1bhqPz9FBZXbeN9DUtxg@public.gmane.org>
The Utilite Pro has a mmc card slot connected to the usdhc3
controller. There is no card detection until hardware revision 1.3.
Add support for it and signal the controller with the broken-cd
property that polling has to be used to detect a card.
Signed-off-by: Christopher Spinrath <christopher.spinrath-vA1bhqPz9FBZXbeN9DUtxg@public.gmane.org>

Notes:
Changes since v1:
- enhance commit message to explain to the broken-cd property
