The newest revisions of A388-GP (v1.5 and higher) support only DAT3-based card detection. Revisions < v1.5 based on GPIO detection via I2C expander, but this solution is supposed to be deprecated on new boards. In order to satisfy all type of hardware this commit changes card detection to use software polling mechanism. Also a comment is added on possible card detection options in A388-GP DT board file.
