From: Ohad Ben-Cohen <oh...@ti.com>
Make it possible for board files to give the
host controller two handlers needed for emulating
card detect events in software:
* The virtual_get_cd handler will allow the host
controller to query the status of the software
card detect (for the given controller/slot).
* The register_embedded_control will allow the host
controller to register handlers that will be used by
board devices to:
1. trigger a software card detect event
2. set private data (e.g. device context) that can later
be used by an sdio function driver
