On the DXR2 board (AM335x using MUSB) the USB compliance test suite
(USB 2.0 Command Verifier) will cause the board to crash and reset
upon the "BOS Descriptor Test - Addressed state". Here the output
from the DRX2 while running this test:
GADGET DRIVER: usb_dnl_dfu
musb-hdrc: peripheral reset irq lost!
composite_setup (776)

Resetting CPU ...
resetting ...
By adding the case statement for USB_DT_BOS and therefore not running
into the default case (jump to unkown label) this crash is fixed.
