 *New ioctl has been add:
 * [Alex Lemberg] "MMC_FFU_INVOKE - transfer the new Firmware data from user spac[Alex Lemberg]space
 	to the eMMC deivce and install the new image[Alex Lemberg] firmware.
* This solution allows to:
- Complete eMMC 5.0 FFU procedure as an atomic operation, without being interrupted by other IO requests
- Not limited Firmware data size. Using Multiple Write operations.
- Support of both EXT_CSD_MODE_OPERATION_CODES modes [Alex Lemberg]
* The solution is using "udev" device manager to transfer FW data from user space to eMMC driver [Alex Lemberg]
* Pre-existing functions from mmc_test were used in this solution.
