mmc_send_status() is currently used to poll the card until it is ready, not actually returning the status of the card. Make it return the status and add another function to poll the card. Also remove the 'extern' declaration in the mmc-private.h header to comply with the coding standard. Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>
