mmc: Allow the tmio_mmc mfd driver to specify get_cd handler

Browse Source 
Some controllers, supported by the tmio_mmc driver do not have the card
detect pin of a slot connected, so that polling needs to be used and
card detection is handled by other means.
This patch exposes a get_cd hook for that purpose.
