264	As it was previously discussed on mailing list, direct gpio pin muxing should be replaced by proper pinctrl. It's in review at the moment , D14104. I added dependency for this review.
539	It's OK in some cases to prevent detach of the device with EBUSY but in this case do not destroy mutex, because it's still going to be required.

Removed all of the ''swap pins'' stuff.
Not destroying the mutex in bcm_sdhost_detach().
Added comment about pin configurations. Without the pull-ups the card will not be recognized !
