U-Boot USB functionality broken in u-boot-qoriq_2017.07

I just updated the U-Boot to the 2017.07 version, and the USB drivers are not enumerating any devices on the USB hub.  This was working properly in 2017.03.  The board is loosely based on P1021RDB, the USB functionality was working consistently in previous versions.   The hub connects a mass storage device (eMMC bridge) and an Ethernet MAC.
