MLK-10932-3 common: autoboot: need to disconnect with pc for usb boot
For USB boot, eg, mfgtool programming case, some laptops/pcs
may not work properly if the board do not disconnect until
linux kernel usb driver initialization process, finishes the
ROM code connection at u-boot can fix this problem, and this
was the original work flow when mfgtool flow was introduced at
u-boot.
