[PATCH] USB: Eagle and ADI 930 usb adsl modem driver

A driver for USB ADSL modems based on the ADI eagle chipset using the
usb_atm infrastructure.

The managing part was taken from bsd ueagle driver, other parts were
written from scratch.

The driver uses the in-kernel firmware loader :
- to load  a first usb firmware when the modem is in pre-firmware state
- to load the dsp firmware that are swapped in host memory.
- to load CMV (configuration and management variables) when the modem
boot. (We can't use options or sysfs for this as there many possible
values. See
https://mail.gna.org/public/eagleusb-dev/2005-04/msg00031.html for a
description of some)
- to load fpga code for 930 chipset.

The device had 4 endpoints :
* 2 for data (use by usbatm). The incoming
endpoint could be iso or bulk. The modem seems buggy and produce lot's
of atm errors when using it in bulk mode for speed > 3Mbps, so iso
endpoint is need for speed > 3Mbps. At the moment iso endpoint need a
patched usbatm library and for this reaso...
