MA-12283-2 fix issue of imx6 boot from SD card when use uuu 

get_boot_device() for imx6 series can't judge the chips is boot from USB
or not. So, when use uuu, "bootcmd" parameter will get the same value as
boot from SD card, so if the SD card has image in it, uboot will not
enter fastboot mode when use uuu. This patch use is_boot_from_usb(void)
to judge whether boot from USB then change the "bootcmd" parameter
accordingly.
