This patch adds support for isochronous out transfers to the HWA. The primary changes are: 1. Add a isoc_pack_desc_urb field to struct wa_seg. This urb is used to send the isochronous packet info message to the HWA which describes the isoc data segment(s) that will be sent as the payload of the transfer request. 2. Use the URB iso_frame_desc field to populate the isochronous packet info message and data segments sent to the HWA. 3. After the data is sent and transfer result is returned from the HWA, read the isoc packet status message from the HWA. The contents of the isoc packet status message are used to set the iso_frame_desc status and actual_length fields in the original isoc URB. This feature required the addition of a some state tracking variables in struct wahc so the dti_urb knows what type of packet it expects to receive next.
