mmc: davinci: request gpios using gpio descriptors
Request card detect and write protect gpios using the provided API
by mmc core.
If a gpio is provided for card detect, we don't need to poll.
So only use polling when a gpio is not provided.
Once all pdata users register the gpios using gpio descriptors,
we could remove the platform callbacks.
