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.
