Please remove useless dgrs driver

An official email from digi.com to Andres Salomon [off-list ref]
explained:

 Dear Andres:

 After further research, we found that this product was killed in place
 and never reached the market.  We would like to request that this not be
 included.

Copy at http://wiki.debian.org/KernelFirmwareLicensing (this was discovered
during research into firmware licensing).

The drgs driver is useless (no hardware to drive) and should be removed.
The files which should be deleted from the tree are:
        drivers/net/dgrs.c
        drivers/net/dgrs.h
        drivers/net/dgrs_es4h.h
        drivers/net/dgrs_plx9060.h
        drivers/net/dgrs_i82596.h
        drivers/net/dgrs_ether.h
        drivers/net/dgrs_asstruct.h
        drivers/net/dgrs_bcomm.h
        drivers/net/dgrs_firmware.c

It will probably also be necessary to delete some stuff from drivers/net/Kconfig
and drivers/net/Makefile, but I assume that this will be trivial for any
net maintainer.

Thanks in advance for doing this.
