From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx> Automatically packet start by usbhs_pkt_push() was useful. But the pushed packet will be called twice if new packet was pushed on usbhs_pkt :: done callback. (1st is called by usbhs_pkt_push(), 2nd is called by usbhsf_pkt_handler()) This patch disables automatic packet start, and clarified packet start timing.
