Some sdio wifi modules have not been working reliable with the sunxi-mmc host code. This turns out to be caused by starting new io-rw commands while the card signals that it is still busy processing a previous command. This commit adds card-busy detection to the sunxi-mmc driver which together with recent core changes to check card-busy before starting io-rw commands fixes the wifi reliability issues on the Cubietruck and other sunxi boards using sdio wifi.
