fastboot: add support for continue command
The fastboot continue command is defined to exit fastboot and continue autoboot. This commit implements the continue command and the exiting of fastboot only. Subsequent u-boot commands can be processed after exiting fastboot. Autoboot should implement a boot script such as "fastboot; mmc read <...>; bootm" to fully implement the fastboot continue function.
