Mark switch cases where we are expecting to fall through.
This patch fixes the following warning (Building: tct_hammer_defconfig arm):
drivers/usb/gadget/udc/s3c2410_udc.c:314:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
drivers/usb/gadget/udc/s3c2410_udc.c:418:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
