USB-serial updates for v4.7-rc1

Browse source 
These updates fixes a number of issues where resources were not properly
 released on probe errors. Included is also a fix for hardware
 flow-control disable for cp210x.
 
 Support for Moxa UPort 11x0 is added to the ti_usb_3410_5052 driver, and
 included are also some general code clean ups.
