MLK-23361 usb: cdns3: gadget: reset endpoint before set DEVDS On CDNS3 usb, the IOC interrupt for IN is triggered when data move from memory to FIFO, but not for the transfer completion. When running fastboot command "continue" to disconnect USB device. The last message "OKAY" sent from device setups a callback to IOC interrupt handler and disconnect with host in this callback. However, the real transfer hasn't finished due to host doesn't send IN at that time, it causes the error at host side. This patch will reset all enabled endpoints in pull up before disable the device mode. The reset checks the EP_STS.BUFFEREMPTY bit to ensure data has sent to host.
