ea6db90e75 USB: serial: ftdi_sio: Add support for ICP DAS I-756xU devices
A Fedora user reports that the ftdi_sio driver works properly for the
ICP DAS I-7561U device.  Further, the user manual for these devices
instructs users to load the driver and add the ids using the sysfs
interface.

Add support for these in the driver directly so that the devices work
out of the box instead of needing manual configuration.

537b8a8695 Revert "USB: serial: add Moxa UPORT 11x0 driver"
This reverts commit 0b2b093ad4.

Turns out the MOXA vendor driver was basically just a copy of the
ti_usb_3410_5052 driver. We don't want two drivers for the same chip
even if mxu11x0 had gotten some much needed clean up before merge. So
let's remove the mxu11x0 driver, add support for these Moxa devices to
the TI driver, and then clean that driver up instead.

4152b387da USB: option: fix Cinterion AHxx enumeration
In certain kernel configurations where the cdc_ether and option drivers
are compiled as modules there can occur a race condition in enumeration.
This causes the option driver to enumerate the ethernet(wwan) interface
as usb-serial interfaces.
