Adding card detect callback function and card detect configuration function for MMC1 Controller.
Card detect configuration function does initial configuration of the
MMC Control & PullUp-PullDown registers of Phoenix.
For MMC1 Controller, Card detect interrupt source is
twl6030 and the card detect call back function provides card present/absent
status by reading MMC Control register.
