Change from EHCI to xHCI on the DFI BayTrail SoM.
The xHCI USB hub is connected to an GPIO on the DFI BayTrail SoM. For
correct operation, it needs to get reset upon power-up. Otherwise it
may happen that the hub is not detected after a software reboot. This
patch also configures this GPIO in the dts for correct operation.

xHCI spec says: the values of the 'route string' field shall be

device slot, and shall not be modified by any other command.
So far U-Boot does not program this field, and it does not prevent
SS device directly attached to root port, or HS device behind an HS
hub, from working, due to the fact that 'route string' is used by
the xHC to target SS packets. But in order to enumerate devices
behind an SS hub, this field must be programmed.

on the xHCI controller:
scanning bus 0 for devices... cannot reset port 3!?
But neither of the two USB ports is routed to xHCI root port 3.
Adding some debug information shows that xHCI port 3 PORTSC register
mysteriously reports both CCS = 1 and CSC = 1.
This is not seen every time. After increasing the timeout to wait
for power to become stable, the issue is gone. So this indicates
current default USB power-on delay (20ms) might be at a critical
region where power is stable/unstable. U-Boot provides a mechanism
