hcd_ddf_new_device refactoring

This long function is now split into parts. Instead of passing dozens of arguments, it now creates the usb_dev_t right away, and uses that to pass it along. The address_device part is now modifiable by drivers.

There is still a work to be done. The biggest problem I see is in the addressing - currently, there is usb_address_t, and for high speed transaction translating there is another address. For (near) future extensibility, we should pass address as a structure. Or even better, make a way how to reference a device, maybe in a similar way how we work with endpoints.
