usb: dwc2: gadget: DDMA transfer start and complete

Browse source

Update transfer starting dwc2_hsotg_start_req() routine with call of
function dwc2_gadget_config_nonisoc_xfer_ddma() to fill descriptor
chain.

Add call of dwc2_gadget_get_xfersize_ddma() in
dwc2_hsotg_handle_outdone() and dwc2_hsotg_complete_in() interrupt
handlers for DDMA mode to get information on transferred data from
descriptors instead of DXEPTSIZ.
