omap4: pandaboard: fix up mmc card detect logic

For MMC1 Controller, card detect interrupt source is
twl6030 which is non-gpio. The card detect call back function provides
card present/absent status by reading MMC Control register present
on twl6030. This functionality was introduced in mfd tree on
track to kernel.org

Sync pandaboard to the same and make mmc work.
