usb: musb: gadget: enable autoclear for OUT transfer in both DMA 0 and DMA 1

This patch fixes one bugs of OUT transfer in double buffer case:

	-the current code only enable autoclear for dma mode 1, and not
	for dma mode 0

Without this patch, test #5 of usbtest can't be passed if we
configure musb as g_zero and use fifo mode 3 to enable double
buffer mode.

With this patch and the following patch(fix dma length),
on my beagle B5, test#5(queued bulk out) may go beyond
18Mbyte/s(seems dma mode 0 is quicker in double buffer case)
if musb is configured as g_zero and fifo mode 3 is taken, follows
the test command:

    #./testusb -D DEV_NAME -c 1024 -t 5 -s 32768 -g 8   [1]

Also I have tested this patch can't make g_ether broken.
