Staging: Add support for Flarion OFDM usb and pcmcia devices.

This drivers add support for following devices:

(usb)-> Qleadtek FLASH-OFDM USB Modem [LR7F04]
     -> Qleadtek Express Card
     -> Leadtek Multi-band modem HSDPA

Sources for usb:
https://sourceforge.net/projects/ft1000/files/ft1000_usb/ft1000_usb_v01.04.tar.gz/download

(pcmcia) -> Multimedia Net Card

Sources for pcmcia :
https://sourceforge.net/projects/ft1000/files/ft1000_pcmcia_2.6.30-2.6.31.tgz/download
