usb: musb: gadget: only enable AUTOCLEAR in double buffered case
commit 633ba7876b96ec339ef685357e2f7c60b5a8ce85 broke g_file_storage functionality by enabling AUTOCLEAR on all cases without caring for all gadget drivers. This patch will only enable AUTOCLEAR if our endpoint's FIFO was configured with double buffering support. Note this is not a complete fix, double buffered case still doesn't work always, but that hasn't been working for quite some time. Other than reverting the entire commit and breaking testusb with double buffered case again, I decided it was better to fix the single buffered case and spend more time fixing double buffered case properly.
