This adds support for two additional boot modes on the i.MX7D SoC, which
is most useful when doing U-Boot development on this chip.
1. "bmode usb" can be used to force the ROM boot loader's serial
2. "bmode normal" can be used to revert to the normal boot mode
as specified by fuses and BOOT_MODE pins
