libpayload: Redirect USB slave init through controller driver

xHCI requires special treatment of set_address since it determines
the device number itself (instead of the driver, as with the other
controllers). The controller also wants to validate a chosen device
configuration and we need to setup additional structures for the
device and the endpoints.

Therefore, we add three functions to the hci_t structure, namely:
  set_address()
  finish_device_config()
  destroy_device()
Current implementation for the Set Address request moved into
generic_set_address() which is set_address() for the UHCI, OCHI and
EHCI drivers. The latter two are only provided as hooks for the xHCI
driver.

The Set Configuration request is moved after endpoint enumeration.
For all other controller drivers nothing changes, as there is no other
device communication between the lines where the set_configuration()
call moved.
