Add support to set/get mmc_host private embedded data. This is needed to allow software to dynamically create (and remove) SDIO functions which represents embedded SDIO devices. Typically, it will be used to set the context of a driver that is creating a new SDIO function (and would then expect to be able to get that context back upon creation of the new sdio func).
