MicroSD card sockets don't usually have card detect line. This pin is actually not needed for the MMC to work and it is more of a platform design decission to have it. The card detect pin already has a configuration entry of its own: 'mmc0_cd_cfg' so we complete the iomux configuration here and let platforms to include it or not depending on whether the card detect line is routed to the SD socket.

Hello,
All imx28 based platforms except 'bluegiga,apx4devkit' and 'schulercontrol,imx28-sps1', use 'mmc0_cd_cfg' in their mmc configuration so please check whether this patch would break these platforms.
