- addd p_qtd_list_tail to qhd structure for easy queue TD

- move control_request from ehci_data to usbh_device_info_pool
- add test for bulk transfer double (2 consecutive xfers)
- use table (array) structure for class driver, currently included
- refractor extract to function insert_qtd_to_qhd
+ init function
+ install_subtask
--> all class driver function must be declared with WEAK
