Message:

usbhost: refactoring

This commit moves interrupt, status and schedule to bus
operations. Then the purpose of hcd_t is better defined, and split into
hc_driver_t and hc_device_t. hc_driver_t is used to wrap driver
implementation by the library (similar to how usb_driver_t is used to
wrap usb device drivers). hc_device_t is used as a parent for hc_t
inside drivers, and is allocated inside the DDF device node.

To support these changes, some local identifiers were renamed, some
functions were moved and/or renamed and their arguments changed. The
most notable one being hcd_send_batch → bus_device_send_batch.
