ARM: dts: utilite-pro: add mmc card slot support 



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.
