CHROMIUM: qcusbnet: Add gobi3k support.

CHROMIUM: qcusbnet: Add gobi3k support.

This entails:
1) Adding a couple of new vid:pid pairs for known Gobi3k devices.
2) Handling the extra USB interface gobi3ks have
3) Installing a proper 'parent' pointer to help udev emit the correct number of
   device events, and
4) Changing the driver's registration name.

The latter change was requested by upstream when I first submitted this driver.
It is correct, in that the driver's name should reflect that it does not just
drive gobi2ks, but it will require changes in userspace to match.

BUG=chromium-os:12380
TEST=Adhoc
ls /dev/qcqmi* with both a g2k and g3k present; try 'gobi3k list', too.

File drivers/net/usb/gobi/qcusbnet.c (right):

http://codereview.chromium.org/6672003/diff/1/drivers/net/usb/gobi/qcusbnet.c...
drivers/net/usb/gobi/qcusbnet.c:24: #define DRIVER_VERSION "1.0.110"
As you change the driver do you want to change the version string?

drivers/net/usb/gobi/qcusbnet.c:26: #define DRIVER_DESC "QCUSBNet2k"
Is 2k correct?  gobi?
