ENGR00238300: enhance the download speed for fastboot

1. the new fastboot is an add-on feature, the original fastboot is reserved
2. the new fastboot is a subset of original fastboot, only support "download"
   and "flash" command
3. type "fastboot" in uboot to launch the original fastboot utility,
   type "fastboot q" in uboot to launch the new fastboot utility
