am33xx: Support upstream devicetree USB device
Support musb being probed by ti,musb-am33xx. The non-upstream DT probing
used a wrapper driver that probed ti-musb-peripheral and ti-musb-host.
This wrapper registered as UCLASS_MISC, which is why it is requested in
this board.c file.
With the new devicetree the wrapper that registers as UCLASS_MISC is
gone, instead the UCLASS_USB and UCLASS_USB_GADGET_GENERIC have to be
requested.
