Dell Latitude E5*50 Linux support

Tested on my Dell Latitude E5450 (late 2014) with Fedora 21 64bit

WWAN module

The Dell Latitude E5*50 could have a "Dell Wireless 5809e Gobi™ 4G LTE Mobile Broadband Card" WWAN module. It's based on the Qualcomm Gobi™.

Name | Dell Wireless 5809e Gobi™ 4G LTE Mobile Broadband Card ID | 413c:81b1 Kernel module | qcserial

I created a udev rule which loads the qcserial module, switchs the bConfigurationValue from 2 to 1 and add the new device id 413c:81b1 to the qcserial driver.
