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.
Signed-off-by:
If platform_data lacks init() callback (solely used to request
card-detect interrupt), we mark the host as MMC_CAP_NEEDS_POLL.
get_cd() host operation provided to optimize polling.
