mmc_spi: add support for card-detection polling

This patch adds new platform data variable "caps", so platforms
could pass theirs capabilities into MMC core (for example, platforms
without interrupt on the CD line will most probably want to pass
MMC_CAP_NEEDS_POLL).

New platform get_cd() callback provided to optimize polling.
