usb: device_next: Reduce code size on Full-Speed only configuration

Browse source 
Allow compiler optimizations to remove High-Speed handling code. Knowing
that maximum operating speed is Full-Speed allows to reduce bulk buffers
from 512 to 64 bytes. More RAM optimizations are possible but this
commit only gets the low hanging fruits.
