staging: Beeceem USB Wimax driver

The Sprint 4G network uses a Wimax dongle with Beecem
chipset. The driver is typical of out of tree drivers, but
maybe useful for people, and the hardware is readily available.

Here is a staging ready version (i.e warts and all)

0. Started with Rel_5.2.7.3P1_USB from Sprint4GDeveloperPack-1.1
1. Consolidated files in staging
2. Remove Dos cr/lf
3. Remove unnecessary ioctl from usbbcm_fops

Applied patches that were in the developer pack, surprising
there were ones for 2.6.35 already.

This is compile tested only, see TODO for what still needs
to be done.
