With a previous patch, the usb_driver suspend/resume callbacks got
overridden and were never called if a usb_serial driver defined them.
This patch fixes the opticon driver to move the suspend/resume callbacks
into the usb_serial_driver structure where they will be properly called.
It then removes the unused usb_driver structure.

Currently, the register prefixes in the driver seem to be mixed: the
capability registers are the ones that contain capability information,
such as number of hardware endpoints, while the registers that are
used to program the controller are called operational registers.
Normally, capability registers start at 0x100 offset of the register
window and are followed by operational registers. In some versions,
however, capability registers start at 0x0 offset.
This patch renames the register and adjusts their offsets appropriately,
leaving the possibility of having a non-standard capability offset.
I couldn't find any mentions of the TESTMODE register anywhere, so I
suspect it might only be enabled in chipidea internal versions of the
controller and I'm really inclined to remove it from the driver or at
least hiding it behind a config option.

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.

This patch (as1550) fixes a bug in the usb-serial core that affects
the ftdi_sio driver and most likely others as well. The core
implements suspend and resume routines, but it doesn't store pointers
to those routines in the usb_driver structures that it registers,
even though it does set those drivers' supports_autosuspend flag. The
end result is that when one of these devices is autosuspended, we try
to call through a NULL pointer.
The patch fixes the problem by setting the suspend and resume method
pointers to the appropriate routines in the USB serial core, along
with the supports_autosuspend field, in each driver as it is
registered.
This should be back-ported to all the stable kernels that have the new
usb_serial_register_drivers() interface.
