On the iMX platforms the USB boot is in fact boot from USB serial download and not from a USB mass storage. So returning BOOT_DEVICE_USB typically doesn't make sense as USB SPD is then used to continue booting, for this we need to return BOOT_DEVICE_BOARD.
Still return BOOT_DEVICE_USB when USB mass storage support has been built in the SPL. With USB-C on both side, the programmer could switch back to device mode and use the exposed mass storage device after the serial download finished.
