Current ring buffer processing logic assumes every transaction
will be submited to physical device before next transaction
coming. So it use two states 0 (free) and 1 (used) to represent
the state of every data block in the ring buffer. With the help
of the two state, the ring buffer could accept and process data
normally.
But this logic is not proper for ISOC transfer, which generally
submits many transactions even none of them arrive the physical
device. So this patch uses three values to represent the state
of data block in the ring buffer:
USB_XFER_BLK_FREE: this block could be filled with new data;
USB_XFER_BLK_HANDLING: this block is submited to physical device
but response from device is still not received;
USB_XFER_BLK_HANDLED: this block has been processed by physical
device.
The new logic will do different things for each state, which will
make the ISOC transfer work successfully.

For the purpose of USB port mapper, change struct usb_devemu to
common interface between HCD layer and USB device layer.
Besides, implements ue_init/ue_deinit/ue_info for port mapper.
