Subject: [PATCH 3/3] mmc: mxs-mmc: add broken-cd property

According to bindings documentation for mmc, the property 'broken-cd'

can be used to indicate card-detection is not available and polling

must be used instead. This patch retrieves this property

and sets a custom flag. On the get_cd() hook, it returns 1 if

the flag is set, to always assume the card is present.
