gpxe: delete long since obsolete snapshot of gPXE

gPXE has been deprecated in favor of iPXE for many, many years now.
It is much better than users get it directly from the iPXE project,
since we should no longer need any special modifications for Syslinux
use.

- * 3c90x.c -- This file implements the 3c90x driver for etherboot.  Written
- * by Greg Beeley, Greg.Beeley@LightSys.org.  Modified by Steve Smith,
- * Steve.Smith@Juno.Com. Alignment bug fix Neil Newell (nn@icenoir.net).
- *
- * Port from etherboot to gPXE API, implementation of tx/rx ring support
- * by Thomas Miletich, thomas.miletich@gmail.com

- *
- * REVISION HISTORY:
- *
- * v0.10	1-26-1998	GRB	Initial implementation.
- * v0.90	1-27-1998	GRB	System works.
- * v1.00pre1	2-11-1998	GRB	Got prom boot issue fixed.
- * v2.0		9-24-1999	SCS	Modified for 3c905 (from 3c905b code)
- *					Re-wrote poll and transmit for
- *					better error recovery and heavy
- *					network traffic operation
- * v2.01    5-26-2003 NN Fixed driver alignment issue which
- *                  caused system lockups if driver structures
- *                  not 8-byte aligned.
- * v2.02   11-28-2007 GSt Got polling working again by replacing
- * 			"for(i=0;i<40000;i++);" with "mdelay(1);"
- *
