This reworks the usb_serial_register_drivers() and
usb_serial_deregister_drivers() to not need a pointer to a struct
usb_driver anymore.  The usb_driver structure is now created dynamically
and registered and unregistered as needed.

This saves lines of code in each usb-serial driver.  All in-kernel users
of these functions were also fixed up at this time.  The pl2303 driver
was tested that everything worked properly.

Thanks for the idea to do this from Alan Stern.

This patch (as1551) cleans up the PM-related entries in the usb_driver
structures of the various USB serial driver modules.  Those entries
are now filled in by the usb-serial core during driver registration,
so they don't need to be initialized explicitly in the source code.

The same is true of the one remaining no_dynamic_id entry.

reset_resume remains a small problem, because the serial core doesn't
support it.  The patch ignores these entries.

Add support for Chinese Noname HSPA USB modem which is apparently
manufactured by a company called ZD Incorporated (based on texts in the
Windows drivers).

This product is available at least from Dealextreme (SKU 80032) and
possibly in India with name Olive V-MW250. It is based on Qualcomm
MSM6280 chip.

I needed to also add "options usb-storage quirks=0685:7000:i" in modprobe
configuration because udevd or the kernel keeps poking the embedded
fake-cd-rom which fails and causes the device to reset. There might be
a better way to accomplish the same. usb_modeswitch is not needed with

Huawei use the product code HUAWEI_PRODUCT_E353 (0x1506) for a
number of different devices, which each can appear with a number
of different descriptor sets.  Different types of interfaces
can be identified by looking at the subclass and protocol fields

Subclass 1 protocol 8 is actually the data interface of a CDC
ECM set, with subclass 1 protocol 9 as the control interface.
Neither support serial data communcation, and cannot therefore
be supported by this driver.

At the same time, add a few other sets which appear if the
device is configured in "Windows mode" using this modeswitch
