This allows the hid drivers to be independent from the transport layer. The patch was constructed by replacing all occurences of usbhid_submit_report() by its hid_hw_request() counterpart. Then, drivers not requiring USB_HID anymore have their USB_HID dependency cleaned in the Kconfig file. Finally, few drivers still depends on USB_HID. Many of them are requiring the io wait callback. They are found in the next patch.
