Ian Lepore 78906a722f Add new helper routines for sdhci bridge drivers that use gpio pins for
card presence and write protect switch detection.

A bridge driver just needs to call the setup routine in its attach(), the
teardown in its detach(), and write a couple tiny glue functions to connect
the sdhci interface functions to the new helper functions.  This is not
extensively documented, but multiple examples will exist real soon.
