This commit merges support for USB 3 and generally refactors, fixes,
extends and cleans up the existing USB framework.

Notable additions and features:

• new host controller driver has been implemented to control various xHC models (among others, NEC Renesas uPD720200)
• isochronous data transfer mode
• support for explicit USB device removal
• USB tablet driver
