[PATCH] MMC/SD improvements

[Sascha Hauer]

- make sure the mci*.probe parameter is always present and so that scripts
  can rely on it.
- let setting of the parameter be succesful when there is a card detected,
  even when it was present before
- Add proper card present callback for host drivers so that we can give
  a meaningful message in the framework.
