This is now set by the usb-serial core, no need for the driver to
individually set it.

Thanks to Alan Stern for the idea to get rid of it.

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.

Gobi 1000 devices have a different port layout, which wasn't respected
by the current driver, and thus it grabbed the QMI/net port.  In the
near future we'll be attaching another driver to the QMI/net port for
these devices (cdc-wdm and qmi_wwan) so make sure the qcserial driver
doesn't claim them.  This patch also prevents qcserial from binding to
interfaces 0 and 1 on 1K devices because those interfaces do not
respond.

module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

this patch to qcserial.c enables the Diagnostics Monitor
and NMEA GPS ports on Qualcomm Gobi 2000 devices.

A Gobi 2000 device will provide 3 serial ports:
        # /dev/ttyUSB0 -> Diagnostics
        # /dev/ttyUSB1 -> 3G Modem
        # /dev/ttyUSB2 -> NMEA GPS port

* The Diagnostics Monitor uses Qualcomm's DM protocol; I used
  libqcdm (ModemManager) to talk to it, found it working, but at
  least DM commands 12 and 64 are not implemented on my device
  (Gobi 2000 built into Thinkpad x100e).

* Functionality of the 3G Modem port remains unchanged.

* The GPS port and how to enable it has been confirmed now in the
  Gobi 3000 source code at:
	https://www.codeaurora.org/patches/quic/gobi/
  Enable/disable GPS via:
        echo "\$GPS_START" > /dev/ttyUSB2
        # use GPS
        echo "\$GPS_STOP"  > /dev/ttyUSB2
