serial gadget: enable/disable on request
- add a usbserial command to enable/disable the serial gadget - allow dfu and usbserial to cohexist in the same barebox - add a timeout in u_serial so that we don't get locked if the user enable usbserial from a UART console but doesn't consume the data on the usbserial port created on the PC - remove debug or verbose printf - tested on i.MX25 & i.MX35 & usb-a926x Signed-off-by: Eric Bénard <eric@eukrea.com> Tested-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
