mmc: davinci: Add support for set_power callback
Some devices connected to the MMC bus are power controlled by external means. For instance, an SDIO device may be powered down/up by an external gpio line. In order to avoid toggling power from within the MMC host driver, add a set_power callback function, which will be called by set_ios upon powering down/up.
